Every week, all week long, scores of climbers, climbing guides, and their clients pour through the gate, many of their vehicles sporting Access Fund stickers.
Boulder, Colorado, the corporate home of the Access Fund, is two and a half hours away, three at the most.
There is not a single established trail leading to any of the dozen crags inside and surrounding the canyon.
There has not, this year, been an Adopt-A-Crag in Elevenmile, nor is there any sign that there has been one since before the fires of 2012.
My fellow campground hosts and employees had never heard of such a thing, save some efforts by Colorado College to shore up the canyon's two hiking trails, one of which is a prime climbing access highway that sees little or no climber maintenance.
The pretty much unanimous sentiment in the local community and among the service personnel of the several government and private agencies that administer this land is that climbers leave trash and impact while trying to camp without paying, which is when they usually abandon burning fires; either that, or while arguing about leashing their dogs and paying the day use fees 'because we came in at night'.
So keep sending in that $100 every year, although I think that's pretty steep for a bumper sticker and T-shirt, if you've got it, flaunt it.
It's obviously doing a lot of good in the AF's home state; how about yours?
