We found a park by the water where Russ took a birthday run, then we showered and had some breakfast, and headed north to get away from the heat.

We had reservations to spend the night at a nearby winery, courtesy of Harvest Hosts. After inspecting the place around 11 am, it looked like a very hot place to spend the day. We passed, and blazed northward, heading for Canada. The temps, however, remained astoundingly high. We stopped at a rest area around 3:30 in the afternoon to take a nap, and the thermometer read 97. I slept like a log, despite that.
We targeted Mackinaw as our next destination, assuming it, too, would be a cute seaside town. It was more like Pier 39 -- very tourist trappy as opposed to tourist friendly. But the weather here was much more fair, around 82, so we walked the dogs by the great lake. Lizzie surprised us by heading right for the water. Got her paws and belly wet without fear or worry (unlike the other dog). She is always a surprise.
In the end we ended up at a casino on the upper part of Michigan called Kewadin. A dirt parking lot, with other travelers.
