Rocksnot is a no kidding threat- I've seen some smaller streams lose a lot of the fish and frog population in the past few years due to that junk. I'm afriad we've waited too long and enforcement will be less than stellar for budgetary reasons- just like milfoil.

I don't think anyone cares if you felt insoles to keep your feet warm, but I would ask you to wash them before you put them in my rivers, thank you. And your socks. Foot fungus bad. :P

Although if you are fishing in only your socks you'll probably get fined for it, and told not to try to be cute.
