I've never been to one. I'd probably (actually, I'm SURE I would be) be impressed, but then, I'd get buyer's lust and then just discouraged because I neither have the personality nor drive to do something as wonderful as they show at the "show".
But I do admire the quilts I see at local fairs--years and years ago we were at the AK state fair and I loved looking at the quilts there--that was before I did much quilting at all.
