Having H/B sites doesn’t guarantee that you wouldn’t be turned away.....I’ve never seen anyone turned away.
One problem with a H/B database is that H/B sites are provided by private, city, county, state and various federal agencies. Also, it changes over time, so keeping it up to date would be a nightmare.
Note that right here on the ACA site is a list of no-turn-away policies by state.
Thanks for the link to the list. I couldn't find it earlier.
I don't think it would be that difficult if you have a say 5-10 volunteers. I mean how many total are in your region? Mine (say TX, OK, KS, MO, AR, & LA) probably less than a handful. Since the sites would initially be user supplied (Rider X would submit the site info) the verification wouldn't take that long, maybe an email or phone call to the appropriate entity. Note: I am not talking about dispersed or stealth camping but official "Hiker/Biker" sites like what is at Yellowstone.
An annual early spring re-verification of the info pretty current.
For the states with a lot of them such as California, one volunteer could be responsible for either the entire state or even North, Central, South regions of California.
I honestly feel ACA could make use of volunteers more. I am sure they could easily get a couple of dozen volunteers to help with various projects like keeping the services GPX database updated.
