Where Is The Rust Belt?

[Crawford]

The southernmost portions of the Great Lakes will generally be "warm enough", even for someone used to Gulf bathwater. Further north, it depends. At my parents cottage near Oscoda, MI (about 2/3 way to the Mackinac Bridge), Lake Huron is still fairly chilly, even in late summer. Fine for me and for most kids, but my wife thinks its too cold. And I'm a cold water wimp (won't swim in Superior).

I wouldn't put Maine and swimming in the same sentence, BTW. Too cold for me. Gets somewhat dicey past Boston. Maybe wading in, but not really a relaxing time in the water, unless you have great conditions. I love the Maine coast, but more for the natural beauty.
