As we drove across Kansas we noticed that almost every little town has a city park right along the highway. They all are similar in design - a road looping off the highway and running for about 1000’ before returning to the highway. They have trees and a rectangle of grass with picnic tables. Some have electricity. Some are free, other have a small fee.
Downs City Park has restrooms, picnic tables, a playground, basketball court, volleyball court, Little League field, and free electric hookups. We plugged in to the electricity on the power pole and spotted more outlets on the fence posts. Stay limit is three days. Park 39.50899, -98.54148
