well, my understanding is that the show starts at 10am and you can buy tix at the door, but they are $10. the website for the show is
www.naias.com I might have a lead on some free tix, so I am going to wait a day or two before I buy mine to see if I can get some free ones.
BTW, I'm told that on the first sat. (13th) it will be absolutely packed!
