IF you can say NO, and IF you have the time to spare, and IF you want to maybe pick-up a trick or two, and IF you are willing to network with a few other Shop Owners (I think that describes my last ATI experience!) - this can be a good experience. There is a class close to me soon and YES, as mentioned, I got a phone call and an e-mail, but I don't have a free day so I blew it off. I have learned a few ticks - and I was told five years ago that I wouldn't last 6 months if I didn't sign up. I'm still here...
