I have visited all shows, but there are many that are of no interest to bead collectors.
Completely agree with Rosanna on the recommendations. If you are also looking for other stuff, like stone beads, beading supplies, lampwork, some other shows might also interest you.
Let me know if you are looking for something specific, let me know and I will try to point you in the the right direction.

Why did I visit all shows? Because I was writing a book about the show. In it you can find interviews with lots of interesting bead people, rock people, etc. Also, you will find some advice on do's and don'ts, transport, etc.
