I was at the same gunshow - didn't see any CZ's either. But, I wasn't really looking for one. I do see CZ's at gun shows every now and then, however, and I've seen some around in local gun shops. The thing is that I don't think any of the LGS's are CZ dealers.
At the gun show the OP was referring to, there was a glut of AR's and .22LR faux military-style rifles, cheap AK's, Taurus', Hi-Points, and the same old revolvers the same old dealers never sell. No interesting handguns at all.
