I was lucky to be living in Montana when they changed their policy.
my first years caught a ton of iffy,biffy rainbow stockies ,usually on a two wooly worm wet fly cast---then I actually had to learn how to fish ...much more satisfy experience for those willing to put in the time and effort but less so for the casuals who just wanted a day on the water and a few fish for the pan...
Butt don't let anyone B.S, you- the REAL reason for the policy change was to placate the tourist industry.Locals were a distant second.
So Farmer might be right for once.
Pa. and Mt. are different situations.
Doubt that Pa.. is that much of a big money tourist destination fishing wise to say the "H" with what the residents want.
