did you post that because that sign is at 13,000' and miles from any trail?
Just had good memories of that place-it popped into my head related to this wilderness discussion. The sign at the border notified us of restriction on what we could do there, plus we had a permit, a form of restricting the number of people. Considering the route and/or lack of popularity, none of the hordes of Half Domers or Whitney day hikers will be there. I do not have a solution for "the problem".
