Dodger Blue all the way!! I had aunts and uncles spread all over the country, and the first MLB game I ever saw was at the old Forbes Field in Pittsburgh where one of my dad's sisters lived. They were playing, you guessed it, the Dodgers. Not a lot of fun that night, as I got stuck behind a steel beam and spent the majority of the game bobbing my head left and right to see, but the seeds had been sewn!
Then, a couple of years later, we spent a month in LA visiting my mom's sister, and went to Dodger games every weekday night and weekend day! This was a huge deal for me because I had a couple of cereal box 45's, (45 rpm cardboard record cutouts they put on the back of Wheaties boxes with tips from MLB players). One was Sandy Koufax, the other was Don Drysdale. I even got to meet them. After that, I was hooked for life!! Plus, it's pretty neat to see them play in the same stadium I went to all those years ago.
I kind of like the Cubbies, too. Who can't help but feel for them? Plus in the 80's, you could watch almost all their games on WGN, and eventually, watch their minor league guys in DM, (it used to be the Iowa Oaks and affiliated with the A's).
