The downtown police building is by comparison to most in the USA a humble and underfunded place. I liked the underground garage though, which probably was used when police vehicles didn't have radios and Bonny and Clyde were on the loose. There is a museum and the renovated but humble city hall next door, both of which were closed at the time of my visit.
The south Missouri region of Harrisonville is something of a boom and bust area because there are lots of vacant buildings left behind by businesses that when bust. A good example of this is the large Bizarre Bazaar building, a big box store that stands empty. It has before it a huge asphalt lot with weeds growing in it, providing space to park an old British double decker bus and an old fire engine. This place is quite near where the new Walmart is located. Down the street is an old Veterans of Foreign Wars post with a sign forbidding the activities youth love--skateboarding, bicycling, etc. The town in general is certainly not friendly to bicyclists, although the downtown area has lots of promise in this regard for it's wide streets and thin traffic.
