This cache is NEAR (not inside) one of the town's most historic buildings, once owned by freight car magnate John H. Barker. If you time it right, you might even be able to take advantage of a guided mansion tour which are offered at certain times of day only.
Once you find the cache, take time to wander around the Uptown Arts District with its boutique shops and local restaurants. Explore the history of the newly created Haskell and Barker Historic District too. See where workers lived, where frieght cars were made, and where folks worshipped and played over 100 years back.
