Powwow held in/around the Ag Building at the Missouri State Fairgrounds in Sedalia, MO July 18th-20th. I've been going with my parents since I was a kid, but now they are in another state & I'm looking to introduce others to one of my favorite events. There's lots of vendors, tribal dancing (Friday @ 1pm; Saturday @ 1pm, 3-5pm, & 7pm; & Sunday @ 1pm), & great Indian fry bread.
Since the Ha Ha Tonka trip is on that Saturday, maybe have a group go Sunday morning (some of the vendors start packing up early Sunday afternoon)?
It's approximately 1 1/2 hours to Sedalia, so leaving by 8:30 Sunday morning would put us there by 10, which gives 3 hours to explore & eat before catching the dancing.
