WI is probably the best bet if you are 1000 miles east of the Rockies, but unless you like hunting and fishing, things get boring real quick around here. That's why I have spent 15 of the last 22 summers in the Sierra
True dat. My wife is a Minnesota native, so for 18 years we've been travelling up there and into Wisconsin for family visits. Every single one of my wife's male relatives (call it 25 or so) is both an avid hunter and an even more avid fisherman. They're particularly enthusiastic about winter ice-fishing, which is a real event for a Georgia boy, I can assure you. You haven't lived until you've ridden in a half-ton pick-up as your giddy brother-in-law drives it off the bank, onto a frozen lake, and out about a mile to find that perfect spot to crank up the ice-auger with the 5-foot bit.
Aside from the obvious differences in style in sub-zero temps, my observation about fishing in the Great White North is pretty consistent with what I've seen elsewhere: fishing is mostly just an excuse to get hammered while appearing productive - not that that's necessarily a bad thing . . .
