Whne you are coming this way on 80/94 take the SR 35 exit North to toward the lake. About 3 miles and you will see the Micgigan City marine. There is a lot of rack in out storage and some great ramps. I think the fee is $5-7.
It;s across Trail Creek from the Bue Chip Casino.
It also would be just South of Route 12 but I think it would be easiest to take 80/94
