On a raft in lake

This is one of those photos that becomes so much better when you read the caption. They're certainly in the lake. This was originally written in pink pen, but is not visible in the scan. This look to be taken in the late 20s or 30s, just based on the swimwear. You have to wonder what happened to this family though the great depression. Did they survive? Or did they go bankrupt? We'll probably never know for sure.
