Went here this past weekend for the A's-Giants spring training game. I must say the bleacher seats are extremely uncomfortable. The seats are too low and make your knees sore after just a couple innings, and I'm only 5-9.
Tickets are cheap, which is how spring training games should be. There is very little shaded seating, so a trip to the shaded picnic area in the LF corner is a must to cool down a little bit.
Parking and access to the stadium are convenient and easy.
