IMHO, one of the things that the hiking community could do RIGHT NOW to help to mitigate the overcrowding problem is to learn and practice dispersed, L-N-T camping. There is a lot of talk about L-N-T, and yet most folks still tend to congregate around shelters. Short of additional regulations that would limit the numbers of people on any given section of trail at any time, this seems like a reasonable alternative. But I could be wrong....
