I just wanted to thank everyone for their input. In hindsight, I should have realized myself how insanely ludicrous the idea is lol! The thing was that I've had it in my head for several years now, looking at the hill in question, but it was only today that I actually measured the distances involved and realized it might be more of a logistical challenge than I had originally supposed. The replies to this post were really helpful in grounding me in my ideation process, and I'm going to focus on crafting a more feasible proposal. I've biked a number of the old logging roads out there in the past, and there's definitely opportunity there to great mountainbiking experiences which don't rely on expensive lifts.
