The Tiffin Bark Park is located within Highland Park, on North Washington Street. It is opened 365 days a year, sunrise to sunset.
The Tiffin Bark Park requires a membership to use it, but thankfully this geocache is located just outside of the park. There is plenty of parking, and stealth may be required.
CONGRATS TO KingBuck aka Buckeye_360 and KingLeo1973 on their FTF!
