We were there last year. I really only wanted to go see Herman's Hermits perform. The whole F&G experience turned out to be a pleasant and unexpected surprise, even for my DS(then 7). They had many hands-on exhibits (outdoors) from various countries that showed what some of their native crops were, how they harvested them, and ways they processed the grains, etc. My DS had fun trying out the many "machines" and techniques that were unique to those countries/crops. The people were extremely friendly, helpful, and fun to talk to. You could tell they enjoyed that people were taking an interest in their customs.
They also had butterfly and ladybug releases, but we missed them.
I enjoyed the topiaries and wonderful beauty!
