Many sport enthusiasts collect rain check tickets. It is interesting to note who was on the roster that day or other interesting tidbits.
What I find most interesting is looking at the roster of players and who the teams were on that particular date. For example this ticket currently selling on Ebay should make you curious to know who was playing the Yankees that day and who actually won.
So if you go to a site that shares the roster and scores for that day it provides a lot of excitement. Click of this site to see the scores and player roster for September 5, 1987.
