tjnthesky, bags on the trail might not be indicative of somebody's dumping.
There is a long standing tradition that if a person takes an extra trash bag and
gets him/herself exhausted he/she can park it on the trail for somebody else to
take it few hundred yards further. Eventually, this bag will make it to the top.
I am beginning to rethink this tradition as I've seen such bags torn by coyotes.
Please describe the bags you found to me. What did they look like?
