Well if you can deal with the weather changes that range from the -20's (Down to -40's in some spots) in the winter to over 100 in the summer come up to Minnesota. You can find several great lakes to fish on, and a lot of them can be found within the Twin Cities alone. If you want to take a 2-4 hr trip up north you will find great deep cold water lakes for bass, Walleye, northern, and musky.
If you want to fish in the winter knock yourself out. Ice fishing can be "Fun" Personally not my idea of fun when you sit on the ice jigging, but hey some others love it,
Plus you can include the northern (or southern) part of the state for hunting. Great Deer, and bear hunting. Duck hunting is starting to migrate to the east towards the Dakotas. We also have wolf hunting here as well.
