Mitts and baseballs

My husband and I had some second-hand baseball mitts and balls in storage and finally got them this spring. Now, we go on walks a few days a week to a local park and play ABC. This is where we play catch until we finish throwing to the tune of the alphabet 26 times, i.e. A - throw - B - throw - C - throw. Et cetera. We do about eight series of this. It's a good workout! And people really like seeing it.
