Hi, Jeeneia - my folks live in SE Minnesota, so we go visit about once a year, and I try to get in some birdwatching. We like the drive up MN 61 along the Mississippi in winter - the base of Lake Pepin is a real bald eagle magnet, though it's probably not so good in spring. There's a bunch of good parks along the route, though - find your way to Red Wing, MN, then follow MN 63/61 south along the river. Check out the St. Paul Audubon newletter for the places they take field trips - they have a bunch of good local sites listed:

Also, whenever I'm making a trip to someplace new, I checkout the local Birdlist on this site to see what local folks are excited about:

Good luck, and good birding!
