I totally see where your coming from as I’ve played your strategy for decades. Although a permit/reservation system is not just about making sure you get a spot it’s also about limiting environmental impact. Yes you can go to another trailhead if OBP/FW path lot is full but when you do OBP/FW is still getting the crap kicked out of it. Same goes with Guyot. Maybe it’s only 30 nights a year but people are still camped in the overflow creating unnecessary impact. Limiting numbers in these areas goes further than just parking your vehicle.I have to disagree with there needs to be a reservation system for certain trailheads. We are talking about 30 days tops out of 365 that it is a zoo, Weekends between late June and Columbus Day Weekend. The rest of the time there is no problem getting a spot. Last Friday I stopped by Lincoln Woods around 10AM and there were still spots open. Same goes for Falling Waters / Old Bridle Path TH.
Everyone on this forum knows getting to popular trailheads early is the name of the game, if FW / OBP is full you can go park at Cannon Tramway lot and hike from there. How difficult is an extra couple of easy miles along the rec path or the Pemi Trail at the beginning or end of hike depending if you choose to ascend or descend Greenleaf Trail from the tram lot?
