Even though they denied my application to become their designated deer killer, lately I've been spending a lot of time exploring Johnson County's network of parks. My latest expedition was to the Ernie Miller Park and Nature Center near the southwestern corner of the county. The charming dirt trail would be more bucolic if the constant roar of traffic from K7 didn't drown out the sound of frightened animals. The site also features a building that hosted children's birthday parties and an art show last Saturday. No deer were spotted.
