Lake wisconsin in near merrimac right? If so that's about 2.5 hrs from me. My girlfriend will be in Madison this summer so I think that might work out as a great place to put a ramp for the summer. When I get around to it I'll send you some pics of the ramp. Let me know if your still interested in keeping it in the water and about what depth of water the ramp would be over. Send me an e-mail at firstname.lastname@example.org
if your still interested.
