Now, for the less technical answer-
Concealed means concealed.
Have a great time at the fair. Be sure to eat something fried.
One more criminal carrying a gun where law abiding citizens are not allowed.
But seriously if you look around the fair there are just way too many people for a gun to really be useful in any situation. For the most part the OKC fair and Tulsa fair have more law enforcement per person than any other place in Oklahoma. Now is that 100% safe? No it does not. Does having a gun make you safer? Only if you have the chance to use it.
Just my thoughts.
