So far, I've been to four. The first one was the PTTP tour w/ Slaughter, Cinderella, Dokken and Poison in June, 2000 in Saratoga, NY. The second was in August, 2000, same tour, just in Augusta, ME.
My third was the Metal Edge Rockfest w/ L.A Guns, Firehouse, Warrant, Ratt (who were awful) and Dokken in August, 2002 in Essex, VT. I got to hang out with the band afterwards.
The last show was August, 2008 in Allentown, PA and I was fortunate enough to talk with Don for the second time, and had a great conversation w/ Jon.
