For the modern SXSW experience, just go to the local supermarket when it's ultra busy and the parking lot is full. Park your car among the rest and just sit in it.
Well that's a shame. Guess I'll visit Austin on some other day.
You'd honestly probably have a better time, unless there was something you specifically wanted to see at SXSW. So many people come into town for it that getting anywhere in the city becomes a nightmare.
Taking this thread way off the original topic now, but yeah. Would love to visit for the music scene—SWSX probably would crowd out what I actually want to get out of the place when I think about it longer than 30 seconds.
