Terms of Use
Last updated 15 August 2026
Bomb Hills is operated by shoben.io. Using the site is free. Sponsorship is a paid service, described in section 12. By using this site you agree to these terms. If you do not agree, do not use the site.
1. What this site is
Bomb Hills analyses public elevation and road data by computer and presents the results. It identifies stretches of public road that slope downward and estimates how fast an object might travel down them. Nothing on this site is a recommendation, an invitation, or an endorsement to skate, ride, or otherwise use any road.
2. Assumption of risk and release of liability
Downhill skateboarding and longboarding are dangerous activities that can result in serious injury, permanent disability, paralysis, or death.
You understand and agree that:
- You are solely responsible for deciding whether to ride any road.
- You knowingly and voluntarily assume all risks of injury, death, and property damage arising from any use you make of information on this site.
- You release, waive, and discharge the operator of this site from any and all claims, demands, damages, and causes of action arising out of or relating to your use of the site or of any road identified by it, including claims based on the operator's negligence, to the fullest extent permitted by law.
- You agree to indemnify and hold the operator harmless from any claim brought by a third party arising out of your use of the site.
3. The data is incomplete and may be wrong
The analysis is derived from elevation surveys collected between 2010 and 2023 and from volunteer-maintained road data. It has no knowledge of traffic volume, speed limits, road surface condition, gravel, potholes, sightlines, driveways, parked or moving vehicles, pedestrians, construction, road closures, private property boundaries, or any law or ordinance. Roads change. Data contains errors. A road shown here may not exist, may not be public, may not be paved, and may be unsafe or unlawful to skate.
The site is provided "as is" and "as available", without warranty of any kind, express or implied, including any warranty of accuracy, merchantability, or fitness for a particular purpose.
4. Obey the law
Many jurisdictions restrict or prohibit skateboarding on public roads. Some streets shown here are private. You are responsible for knowing and following the law and for obtaining any permission required. Nothing here is legal advice.
5. Limitation of liability
To the fullest extent permitted by law, the operator shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, data, goodwill, or for personal injury or death, arising out of or relating to your use of this site, whether based in contract, tort, negligence, strict liability, or otherwise, even if advised of the possibility of such damages. Where liability cannot lawfully be excluded, it is limited to the greater of the amount you paid to use this site, which is nothing, or one United States dollar.
Some jurisdictions do not allow the exclusion of certain warranties or the limitation of liability for personal injury caused by negligence. In those jurisdictions, the exclusions and limitations above apply only to the extent permitted.
6. Minors
This site is not directed at children. If you are under 18, do not use this site without the involvement of a parent or guardian.
7. Acceptable use
Do not scrape the site at volume, attempt to bypass the verification step, interfere with its operation, or use it to harass anyone or to encourage unlawful activity.
8. Third-party data and trademarks
Elevation data is from the U.S. Geological Survey 3D Elevation Program and is in the public domain. Road data is © OpenStreetMap contributors and is licensed under the Open Database License. Base map tiles are from OpenFreeMap; terrain tiles are from the AWS Terrain Tiles open dataset.
Google and Google Maps are trademarks of Google LLC. Apple and Apple Maps are trademarks of Apple Inc. Bomb Hills is not affiliated with, endorsed by, or sponsored by either company. Their names are used only to identify where a link goes.
9. Sponsorship, payment and refunds
Anyone may sponsor a map square. Sponsorship is a one-off payment, priced by the population the square covers, and it buys public credit on that square's map: your name, logo and message, displayed for twelve months from the date the payment clears. It is not a subscription and nothing recurs; the credit stops at the end of the term.
Sponsorship does not buy access, exclusivity or influence. Every mapped town is free for anyone to view whether it is sponsored or not, we map towns on our own schedule regardless of whether anyone has paid for them, and sponsorship never affects how a hill is measured, scored or ranked.
Payments are processed by Stripe. We never see or store your card details. Because the account is shared with our other site, your statement will read SHOBEN.IO followed by BOMBHILLS.
What you are buying. We survey the square, publish every rideable descent we find, and credit you by name with a short message and a link on that map. We do not promise a particular number of hills, or that any of them will suit you.
Refunds. You get a full refund if:
- the survey finds nothing worth publishing;
- we fail to publish the square within 30 days;
- or you change your mind before we publish it.
Once a square is published it is live for everyone and cannot be withdrawn, so sponsorships are not refundable after that point except where the law says otherwise. Ask us and we will sort it out; we would rather refund you than argue.
Your message. We read every sponsor message before it appears and may decline or remove one that is unlawful, misleading, hateful, or promotes anything we would not want next to a map of public roads. If we remove a message we refund you. A link must be to a working site you control.
Sponsorship is arranged directly. Terms, placement and duration are agreed in writing with each sponsor before anything appears on the site. There is no self service purchase.
The maps are for reading, not for bulk collection. The hill data is provided so you can use the maps on this site. It is not offered as a data feed or a database, and automated collection of it is not permitted. The road geometry underneath is derived from OpenStreetMap and remains © OpenStreetMap contributors under ODbL.
10. Changes
These terms may change. Continued use after a change means you accept the revised terms.
11. Governing law
These terms are governed by the laws of the State of Oklahoma, United States, without regard to conflict of law rules. Any dispute shall be brought exclusively in the state or federal courts located in Oklahoma.
12. Contact
Questions about these terms can be sent to the address published on the site's contact page.
Sponsors also accept the Sponsor Terms, which set out what is not allowed and the limits on our liability to a sponsor.
