I always have these on board on the Great Lakes. This is tons of good info on every harbor/marina on the big lakes and what amenities are available or are within walking distance.

You can buy them on-line or at any boat supply store.

As far as the customs thing, I couldn't tell you. There have been plenty of times I wanted to go ashore in Canada but just didn't. We anchored in a little Canadian bay once on the St. Clair River for a swim and found out later that I could have gotten in big trouble. Having lived on the border all my life I can tell you that Canadians are our good friends and we love having you over.

Thanks, will check that out, might get lucky and find one on Ebay, if not, I wil order one new. Our cottage is on an Island pretty much 1/2 way between Canada and the US, lots of US folks there own cottages, and I am good friends with a pile of them, damn good people!

Thanks again!
