I had a nice conversation with my dad when I was asking what they were really doing in this photo. He is pretty sure he was collecting them to edge a garden he'd created. Funny, cause he still collects rocks to make rock walls (and he's made some fabulous ones). He also told me that he got that wagon for Christmas during the war. It was a big deal, because it was really hard to find a metal wagon most kids got wooden ones. His parents must have gotten lucky.
Thanks for looking!
