Have been to about half of the MLB stadiums. We were doing at least one every year (until the baby came last Nov, which has slowed things). I think anything with in 10hrs driving has been accomplished and our honeymoon was all 5 in Cali. In addition to others we have knocked out over the last 9 years. By far our favorite was PetCo in San Diego. Lots of cool things there. After you go to a bunch of stadiums you want the next one to have something different/unique. PetCo looks cool inside with the building fronts (since it is built right in downtown), you can stand behind the left fielder on the field level (if you go out the back of their store), there is a Wiffle Ball field behind the scoreboard for bored kids and a monitor on the back of the scoreboard so parents there can keep up with the game.... out list goes on for this one. Comerica was much nicer than we had planned for. The area around isn't great, but a few bars etc within walking. Miller Park is always at the top of our list as well, partly due to familiarity, but mostly due to the fact it IS a great stadium. New Busch was not good for us. Actaully pretty boring for a new stadium IMHO. We sat on the second level and were much further away than when you would be at Miller Park or most other stadiums. Target Field on the radar for 2011. Could go on and on...
