A few years ago off the BST section here, I bought a Boone Family signed ball which included Ray on the sweet-spot, Brett on the north panel and Bob on the south panel.
I always wanted to add Aaron to it but really wasn't sure how to obtain it. A couple times I wrote the Yankees PR Dept. and asked if there was a way to meet him prior to a game in Baltimore (where I have a Sunday season ticket plan) to no avail.
For some reason, I decided to write them again prior to the Yanks trip into Baltimore in July (directed to a different dept. this time), but the game came & went with no reply...
BUT, the good news was that I received an email about a week after the game from someone on their office staff that they read my letter & they were sure that Aaron would love to sign the ball and to simply send it to them (which I did)....I just got it back a few days ago:
While not being a Yankees fan per se, I'll always remember their generosity in helping me out.
