Yeah, throw out all of the stuff that you (or somebody else) PAID FOR! Yeah, that will sure show ol' Georgie boy! It's not like he didn't get your money already or something...
I say just hang on to the stuff, you never know what life will be like way down the road. Do you know how many people later kicked themselves for throwing out their baseball cards back in the day b/c they were mad at the player and/or team, or because they didn't follow baseball anymore?!?
