I'm headed down to Austin this afternoon and already I'm freaking out that I've forgotten something. Did I pack my phone charger? My iPod? Extra contacts? Toothpaste? Registration info? Etc etc... There's SO MUCH to prepare for, so if you find yourself slightly spazzing out like did, you'll be glad to know that some anal retentive dude has already put together a master checklist for SXSW 2007. It reminds you of everything from your digital camera and extra memory stick to Chapstick and Claritin.
The website is called SXSW Baby and it's pretty resourceful. You can view the entire list here. Trust me, it's worth it. There's some other good info on there as well, so don't hesitate to poke around a bit.
