Sher and I were here back in 2016.
When traveling east on Interstate 40 into Oklahoma from Texas you should take Exit 7 and head south into the town of Erick and Old Route 66. This former boom town was founded in 1901 but fell into trouble after WW II. The main street is filled with several nice old brick buildings that unfortunately are mostly empty.
Of special interest in Erick is the relic adorned “City Meat Market” building. This brick is covered in old signs the likes of which would make any antique picker green with envy. This is the current home to the Sand Hill Curiosity Shop. We did not hit Erick on a day that the shop was open. A local shared that the shop is owned and operated by a pair of characters named Annabelle and Harley, AKA the Mediocre Musicians. They will play and sing for you if you catch them there.
