While most things there will set you back a few bucks, there were some fun things for the kids to enjoy that didn't require a penny. One tent had some lego robots. While not very impressive to me, my Little Brother Mr. B and my niece Little K probably liked them more.
Both of them got to build their own flashlights from some Charter School's tent.
And Mr. B probably liked this one of the best. Future firefighter maybe?
