I would really like to see a real BBQ Festival........One that actually brings in teams to compete and win prizes. They have these competitions all around the country and they attract large crowds. Could you imagine smelling smokers all around the park, and you purchasing a test kit to eat a little something from everyone. Maybe make it the finale to the BBQ and Bluegrass festival they already have.
I'd also like to see a "County Fair" festival......something that people could enter real contests (baking, sewing, etc.). Having multiple venders all over the park where you could buy their goods (breads, cobblers, pies, etc.). Something similar to the harvest festival but make it mainly food related.
Also a major music festival - Bluegrass, country, folk, etc. - make it a "fan fair" of the midwest. Meet and greet opportunities with music legends as well as some of the new artist just trying to get a big break.
Anyway, those are just some of my thoughts....
