Swift Run Dog Park is the greatest place on earth.  Well, Runyon feels that way.  It is located near the intersection of Platt and Ellsworth and across the street from Lillie Park in Ann Arbor, Michigan.  From the City site: "The joi​​​nt city-county Swift Run Dog Park is located at the northeast corner of the Swift Run landfill. It is bounded on the north by Ellsworth Road and on the east by Platt Road. The 10-acre Swift Run Dog Park is maintained in partnership with Washtenaw County with financial contributions from both the city and county."
