I'll be there...since it's about a 15-minute drive from my house.
I have mixed feelings about these large shows. Generally, just more junk and outrageous admission/parking fees. And sometimes the expo center gets so crowded that it takes a half hour or more just to get in; and once in, you have to elbow your way through the aisles--not fun!
On the other hand, I guess one is more likely to find a larger selection of firearms in general, and shotguns in particular, than at the smaller shows.
Anyway, I'll be there Saturday.
