Beaver Lake is a beautiful cruise.
I have pulled a few small bass out, but I was really out there for the exercise and the view.
If you are interested in trying a kayak out, Aquarius Sail in Pewaukee sells Hobie Cats (and others) and John does give people the chance to try them out. He a good guy and really does know the boats.
I think he usually sets up Saturdays on Pewaukee, but he could verify what he can do to get you hooked er, ah I mean show you what you have been missing.
