The only fly shop that I really ever visit is the Bear's Den and if Scott or anybody else there ever gave me any attitude I think my jaw would probably hit the floor. Nicest people you can imagine and will go above and beyond for a 50 cent sale.
The only other place I ever really get fly fishing stuff is when I'm passing through Portland ME, I'll stop at LL Bean. They're always very friendly and helpful too.
My passion for catching fish is eclipsed only by the fish's passion not to be caught.
