At the Strawberry festival in Plant City, there will be signs posted at the enterance stating "NO WEAPONS", but there is NO metal detectors or individuals who do "pat-downs".
With that being said, when the family attends, I always CC. Once I CC'ed my .45, I just made sure I had a good long cover shirt (did alot of bending down due to my kids). A few other times I CC'ed my LCR and will be carrying the .40 when we head there in a few weeks.
