There is a lot of the AT in "No Gun Zones" where something like a NAA Mini Revolver or KelTec .32 could be hidden without much worry of being found but there when needed. There have been a lot of rapes and murders along the trail that never make it to the press as the locals don't want the area to get a bad name....
Many people carry OC...any woman who hikes with no gun or at least OC is out of their minds....(see my signature line)
