143 is the centermost bleacher section at AT&T. It's a fun place to sit but sitting underneath the scoreboard absolutely sucked. You have to turn completely around to read anything and even then, you can't see it so well. There are also no backs to the seats; much like Lambeau Field in Green Bay if you've ever been to a game there. Even the A's don't have bleachers at the Coliseum.
The most annoying part of sitting in the bleachers is the fog horn that goes off and the water that shoots out. Add that to the strong winds from the Bay that blow strongly in the bleachers and all of a sudden, it becomes a very undesirable place to sit.
I always take the BART to the ballpark; so much cheaper than parking. The stop you want to get off at is Embarcadero Station which is about a mile away from the park. If you've never been here before, you're going to enjoy it. This is one of the premier ballparks in Major League Baseball.
