Yeah, UT Shuttles run until about 11:45 pm, although a few routes are paired so the service runs every 30 minutes instead of 10 or 20. Cap Metro buses run most generic routes until midnight and then they start "Night Owl" and "Starlight" routes- 4 or so routes that run until 3 am. The good news- I can stay on campus until 2:15 am and still make it home via the bus, 5 miles south of campus. The bad news- I actually looked that up so I could use it before :-( Anyhow, Cap Metro isn't perfect but it's cheap (free for me, or I think 50 cents at most for anyone else) and they do a pretty good job.
