1958 Outboard Nationals and pictures

A few years ago, I came across this collection on Ebay and took a chance on it. The program is from the 1958 Outboard Nationals at Lakeland but I'm not sure all the photos are from that event. The pictures I assume are from someone from Ohio as most of the boats have the S prefix. Can anyone fill in the blanks? These will be in no particular order.

Those are some fine pictures Dale, but you are right that they must be race courses in Ohio. Looks like from the background they are most likely from two prominent race courses. Lake Hollingsworth is one of the most identifiable race courses there is.
