I'm actually surprised there isn't another post on this topic already, but my cursory search of the site didn't turn up anything, nor did Google.
Actually, my Googling brought me to a pretty interesting (albeit highly nerdy) SABR article from 1981called "Where Spectators Sit to Catch Baseballs", so it wasn't a total washout.
That being said, my 8 year-old son is dying to catch or receive a real live, honest- to-goodness Oakland A's game ball, so I'm doing my fatherly duty and asking my friends here on AN to enlighten me. Where have you had the best luck getting game balls at the Coliseum?
Thanks in advance for your contributions. I hope to put your advice to the test Saturday night.
Let's go Oakland! Clap, clap; clap-clap-clap!
