After much deliberation, we've finally decided we're going to do a potluck style picnic on the fields in front of the state capitol, because what better place to have our international meetup day in Austin than in front of the capitol building itself? We can meet and/or gather near the front of the steps. Look for a tall asian guy (that's me). If you show up later than 6, I'm sure you'll see a large gathering of people (that's us). People can come and go as they please, and afterwards we can do a pub crawl to get our drink fix (no alcohol on the lawn) for all those who are interested (and 21+).
As for parking, I highly suggest carpooling and public transportation. There's not much we can do about this no matter where we go, since there will probably be about a hundred people coming to this.
Hope to see you all there!
