I have about 4. One is a homerun I caught off the bat of Richard Hidalgo. Glad I brought my glove that day.
Other one was in 1990. A coach for the Padres(Pat Dobson) picked up a ball at the old Astrodome and handed to me. He also signed it. I still have it in my room.
Another was given to my mom in 86? Astros vs Mets, Glenn Davis hit a bomb to the warning track(the dome was not big on HR's) and Strawberry caught it and threw it up to her. She kept it and gave it to me recently.
Other one was a shot that landed in the Houston bullpen that Brandon Puffer threw to me. I've been lucky so far, I hope to snag a few more
