I'd certainly attend another. I quite agree with the point that if we don't attend such shows they just won't happen. Warlord seemed to be doing ok business, as dud Colonel Bill (or at least the stands were busy, which may not amount to the same thing).
My big mistake was seeing some Don Troiani ACW books that I'd earmarked to go back for, then forgetting all about them! There were some lovely books there which I very much like to see as shows tend to be the place I get a lot of my books now.
