The Best Of Our Knowledge # 1115 – Think about how you spent your summer vacations when you were a kid. I'm sure there was a lot of swimming and camping and ball playing and bike riding involved.

We'll also spend an Academic Minute not quite that far away...we'll stop at the Moon. For a little sight seeing.
