when i was a kid, i pulled just as much for the Reds as i did for the Angels, my connection being that we lived in ohio for a while. i think i was more passionate for the reds then because of the big red machine and the fact that they were winning while the halos kept spinning their tires in the mud. my friends and i would always wonder when it was going to be the angels turn.
i think where the switch for me really came was when i discovered online message boards in the 90s and the emergence of tim salmon, plus the retirement of johnny bench.
that might make me sound a bit bandwagonish, but i don't care. the reds will always hold a special place in my fandom, but the halos are my team.
