Gary from the Tucumcari Trading Post suggested that I take the short trip East to Endee, NM and visit Russell's Travel Museum. The museum has a great selection of classic American cars, gasoline memorabilia, and Americana memorabilia. Their cars were impeccably restored down to the undercarriages and wheel wells and they had a few newer American classics in their collection.
It is worth the trip if you are traveling East on Highway 40 towards Texas.
