My family recently moved. As we packed, I came across my box of baseballs. I paused to go through them. I have a collection of balls over the years consisting of foul balls, home run balls, batting practice balls and other balls thrown up into the stands. The box is an empty motor oil case, full the top. Each ball had a piece of tape on it listing when and where (if I knew that info) I retrieved it.
I went through each one. I have fielded ten foul balls in four different ballparks and eight home runs in two ballparks. I put each one into a separate sandwich bag, as a few pieces of tape came loose. I was able to piece them back together based on the league president signature on each ball and when that president served crossed with the date on the piece of tape.
I'll be writing soon about each foul ball and home run ball I retrieved, plus other notable ones.
