I finished up the first batch of slides I purchased off eBay last year. A nice surprise was one of the first I scanned in today. It's a picture of several beautiful old cars lined up to catch a ferry across the straits of Mackinac in northern Michigan in 1952. The Mackinac Bridge didn't open until 1957 so in 1952 if you wanted to get from Michigan's lower peninsula to the upper peninsula you had to drive your car onto a big boat. It also looks like you had to wait in line for a while. The Ferry is the S.S. Vacationland.
