I went to Arlington Stadium, the expanded Triple A stadium that the Texas Rangers used until about 1993.

I've also been to the Astrodome for a couple of Astros games. And before some nitpicker tries to claim that the building still exists, it is no longer capable of being a stadium, short of a major remodel after the abuse and demolishment of the interior of the building over the last couple of decades.

I've also been to Royals Stadium, love that ballpark, but it appears it may be a "previous" stadium in the next few years; since it looks like they will move to a new stadium closer to downtown.
