It is what it is.
The Fairgrounds staff has also advised they eradicate pests....so leave your pests at home
They even capture queen bees, and relocate the bees......I was there in June for Back to the 50's and it was hot...no mosquitoes in sight!!
As a beekeeper, I don't find bees to be pests, they are very beneficial and, if you live in the US, you enjoy the fruits of their labor by eating food that they pollinate. And they are live and let live, you leave them alone and they won't bother you
Now, as to mosquitoes ..................................................
