Late to the party (fair ended yesterday), but figured I’d share my experiences if anyone’s curious for next year.
We go every year and for the last 4 at least I’ve carried. I too subscribe to the idea that no “illegal” weapons are allowed and my CCW is legal. Also my understanding is there is precedent with the Florida STATE Fairgrounds trying to restrict carry and failing as it was deemed public property.
My personal experience is I go through the metal detector, it buzzes, then security wands me (usually avoiding wanding my 4 o’clock where I carry) and sends me on my way. This year the lady even made a friendly but big production of having me show her my belt buckle and wanding it to demonstrate that was why the detector was going off! It’s almost like they know I’m carrying but want to put on the security show. Anyhow, never been hassled beyond that, this year I thought the deputy watching security would call me over but he didn’t bother, maybe cause I was with the wife and kiddo.
