I still watch for one very simple reason:
Its still Baseball, and its still a beautiful game (well for every opposing team but i digress), the games which we do win, things will go right, and everything will click, and for one night, the Angels will have played a good game.
All of us Angels fans who were fans before 2002 know what its like to be rooting for a team that was most famous up until then for a movie featuring Danny Glover, and Joseph Gordon Levitt, and we knew that most seasons would end in disappointment.
I watched when we would finish in last place, I watched when the Mariners beat us in the one game playoff, and I will watch this year, even if we end up in last place. I'll bitch and moan and crack Fat Trout jokes, but I still love this team more then any other professional sports team.
