It must not be very difficult to come by tickets behind the plate, because I see different people there practically every night.
They give a lot of those away. One of our PTA members has a friend in the ownership group. She asked for a small team banner to use for a teacher thing, and the owner gave a substantial package of stuff, including a couple of tickets behind home plate to each of several games this week end. It was cool that our PE teacher won one set, cause he actually likes baseball and can in no way afford the $300 seats.
