wow everything you said will actually do nothing, great job. Do you work in congress? I feel your pain and frustration but i dont think thats the answer, i admit i have had similar thoughts. All of your limitations will not get rid of the problem but lessen the trash by a 1% (meant to be a small number not actual) percent margin that will probably be barely noticable.
All you know everybody who gets that once a year overnight permit will all leave some poop for you.
I think education is key. Now what can a class actually do. Well i have been in situations where taking a class and has opened my ignorance/attitude toward a issue. If people did have to take a class, see some nasty pictures, maybe walk out back of ranger station where a setup wag bag area was so they could smell it and see the nasty mock area to simulate what is actually out there, it just might have more of an effect.
Confronting people prior to the issue has power. also by having a class it might convert one person or two in the group who might put pressure on their friends once out in wilderness to live up to the rules.
maybe the class should be longer than 30 min, like the hunters education class. After taking that class i had a different outlook on certain issue. maybe the class should be 8 hrs with a fee that gives people a license. that would weed out people who are once in a while backpackers who dont care about mother nature.
I wont burn you because i feel your pain but i disagree with you on all accounts.
