lawman888...They are all different. The ICCS in St. Louis is the cream of the crop of cuemakers from all over the country, and is mostly about very high end cues. The one in Chicago is a regional show, that will probably not have the ICCS guys there ( could be wrong, but you can check the thread for the Windy City show, as they list the vendors), but will be a chance to see some 'normal' cues and cuemakers. Valley Forge is not a cue show, per se, but a place where you can see a lot of different things, from cues for sale (new and used), to talking to cuemakers about custom cues, to seeing every kind of cue case and pool doodads available. Pick your poison!
