With all do respect the felt ban is worthless.
Didy was in the Norfork and White for years and I personally would fish the White and drive with my boots on to fish The North Fork of the White, Montauk or Bennett on my way home.
Not just me but all my buddies too.
We did this for years and I've been fishing the White and Norfork since the 70's.
If it was going to spread it surely would have by now and certainly would have before the worthless ban was put on.
Legal disclaimer.
I have two pair of wading boots because of the ban though.
Felt in AR, none in MO.
