They can stick their "No Firearms on The Trail". A friend and I did just a 2 day section some time in the late 80's ? It required an overnight stay in one of their trailside yurts. I wasn't but a few weeks before, that 2 people ( I believe a guy and gal) were murdered on the trail by a drifter/vagrant. They caught the guy somewhere near the southern portion, I believe wearing the victims shoes ? Well, we both packed heat, and didn't even care to ask if it was legal. The remoteness of the trail, and especially those yurts for overnight stays, are a prime hunting ground for those intent on ill-will.
There's a website that lists the murders over the years on the trail. Somewhere in the double digits I believe.
