When I was a young teen/kid I used to chase baseball players for their autographs. I think it's legit for teens and kids to do so. However, I remember, there were always a bunch of 40 year old somethings that chased players also. They kinda looked like the comic book guy in the Simpsons. I think that's kinda sad that you would chase some guy who is 20 years younger than you for a mere signature... Sigh.
