We had an amazing visit at the Kit Carson Museum in Rayado, but I just had to see what was around the bend a few miles beyond on NM 21. As it turned out, this was: Miami Lake, a private reservoir just west of the unincorporated “town” of Miami itself. According to Wikipedia, Miami was named for Miami, Ohio—how exceedingly odd—and judging from the results of a Google image search, I did just fine turning around at the lake.
This is a very lightly settled area of New Mexico, which if you think about it is really saying something. I could have taken a nap in the road. The sight of so much water is disorienting, too—where am I, you know?
