We were here during the Indianola Balloon Festival. It is on Hwy 92, a few minutes from Balloon field. It is a first come, first serve, you pick your own spot and pay daily so you can extend your stay as long as you wish. Nice, shaded spots and we managed to keep it cool inside despite the 100 degrees outside. We picked a spot with the playground right outside, our daughter loved it. It is at a fairground though, so you might want to check their schedule as we had a very loud Figure 8 spring car race our last night, but noise doesn't bother us too much. It is also on Hwy 92, which is a little noisy. Internet was however spectacular, which is one of our priorities so we were happy. We camped here in a Fifth Wheel.
Nothing fancy, but the price is right for water/electric hookups. They have a dump site at the park. The park is located on the west side of town on HWY 92 across the highway from an excellant grocery store, try the meat counter. We camped here in a Motorhome.
