I pay $25 per year. I don't agree with all of the things it's spent on, but we live in America, where at least we get to weigh in on such decisions. It is impossible to get millions of humans to agree on anything.
The toilets at trailheads are a good thing, IMO. I do volunteer litter details each time I hike, and at trailheads with toilets there are far fewer tp wads, which are always prevelent at trailheads without them. I removed at least 50 tp wads at the UNH/Downes Brook trailhead recently, but Sabaday Falls trailhead ( which has a toilet ) had only a couple.
A ranger "busted" me cleaning the trailhead at Moat Mt Trail. He explained that if I spent 16 hours doing that in some govt. program, I'd get a free pass. That's less than $2 per hour
It was a kind offer, but that would degrade the sense of pride I feel doing it spontaneously for free.
I don't beleive a fee keeps a single person from hiking. Show me one person who doesn't have $20 for a year of hiking, who hasn't spent money on booze, cigarettes, junk food, lottery, Dunkin Donuts, etc., etc., etc. The entitlement mentality doesn't belong here in the White Mountains.
