I like to fish. For me, my favorite state would be Alaska in the summer time. Specifically, the Kenai Peninsula. I know a few good spots to cast a line there.
2nd would be anywhere in the Florida Keys. There is a great biomass of fish down there. You never know what you will reel in. It's a great winter destination.
Other great destinations are NW Wyoming and the greater Williams/Flagstaff area. Those areas are more scenic than outstanding fishing locations.
