Tthanks for posting Mitch - pleased to hear you are a big fan of the Horns and that you may be moving much closer to the area.
You should take up the kind offers of tickets / accommodations from our generous posters noted above. If you can, you should also allow time to really explore the campus by yourself if you prefer or if you can, with someone that knows the campus and can give you a little history. You can get a tour of the Clock Tower but it has to be set up in advance as there a limited tickets available each day, etc. Also if you have time you should plan to visit the Texas State Capitol that is close by. There are lot's of things to see and do in Austin - these are only 2 suggestions.
In the meantime, please share how you became a Longhorn fan way up there in the frozen tundra of ND.
Hook 'Em!
