I think I can play a practice game or two (or 3) on Thursday and should have my Dark Elves mostly built (so limited proxy) to better test an army than my dwarves.
If it turns out I cant make it on Thursday I'll be at the store all day Friday.
As to location to play, Jeff is going to Corpus, but people from Austin might not travel for Semis (but you run the risk of people like Brandon and Jordan going to Corpus) so its really just a crap shoot on opponents.
I'll try and be there Thurs, but I'll post here if I cant make it til Friday.
