This is a good move in my opinion.
If people weren’t generally ‘trashy’ and took out what they brought in, this wouldn’t be necessary.
I agree.
I was there in 2010 and while it was pretty clean, I still saw the occasional water battle or other trash laying around. I don't understand who does this. I suspect this really won't have much affect on the trash left behind as people will just pack it in and leave it anyway.
I agree. I use a Camelback waterpack and haul in my own. Folks should probably bring a Katadyn or MSR filter if they need more and just process it from streams and lakes on the trail if necessary.
Yep, have plenty of free running water and maybe sell or rent with a higher deposit more permanent containers.
