Jacob W. Wombacher Park is located in Country Club Hills, MO behind city hall. Country Club Hills is a small city in St. Louis County, MO. The park is quite nice and has a basketball-like hoop with a special scoring system that I haven't seen before. There may be muggles at the park so be careful. It is open from a half hour before sunrise to a half hour before sunset. The cache is located in a wooded area nearby with about a 15ft bushwack.
As some have noted, BUG SPRAY would be useful
PS Per the sign to the park, "No profanity" , so watch your language if you are having trouble finding it.
