Madison you could go north, east, or west a few hours and be in good fly fishing.
For fly fishing proximity, UW-Madison is in a primo spot. Just a short drive west and it gets really good.
The abundant hunting and fishing based in Madison likely cost me an extra semester in school Note I was being paid to sell gear and guided a little bit for some of those years, but still. So much at your fingertips.
Don't even need to leave the city: Catching smallies off Picnic point or in front of the Union. Float tubing for muskies and white bass on Monona. Flinging poppers in golf course ponds if you know the right folks.
