Carp Lakes

I want to take a shot next year at fishing carp.  I am interested in lakes/streams north of hwy 29 (north central area) in northern wis. that may hold carp.  Any info would be appreciated.  Thanx

Door County in early summer is where it's at, or so I've heard. 

Green Bay has some truly outstanding carp action, particularly in the spring.  Many years ago, the guy in charge of the fly fishing dept at Bob's Bait Shop used to guide for carp on the Bay.  He said 20 lb to 30 lb fish were common.  Very few people target carp so they get to grow to very old age.
