Yeah, the Austin airport is kinda in the middle of nowhere, and it's miserable to get out of their once traffic picks up. I don't doubt that SA would have a boring airport as well. I was considering just stopping in a town between the two cities to spend a couple of hours (maybe stock up on some road-trip supplies). And the airport here is small, so it's much easier to navigate than say Philly's.
Thanks. I'll take that into consideration for sure. I'm picking a pretty poor time to try to find entertainment at it is.
