Jasper waited patiently at the creek gate on Sunday afternoon, July 20, in the Shirlington Dog Park. In addition to a puppy playground and a deep dog run, the park borders on Four Mile Run in Shirlington. The creek bed is a popular attraction most of the year with the canine populace. The dog park at Shirlington is located at 2601 South Arlington Mill Drive. The park is open daily from sunrise to one half hour after sunset.
