Hey Don,
When I read you were going to Madrid, the first thing I thought of was the scene from Wild Hog's when they are in Madrid, N.M. (pronounced Mad Rid) I grew up a few miles from there and it was a "special" place in the '70's. It's an abandoned mining town that had turned into a hippy commune of sorts. But from Friday afternoon till Sunday night there was a mix of every type character you could imagine, just groovin' and hangin' out. The Saloon was like something from a dream, Cowboys, hippies, dogs, chickens, parrots, snakes.. you name it, They were all there together. Very Cool...
the last time I was there was early 90's I guess. They were still doin' plays and serving libations in the
saloon, and there was guy putting on a wild west show with his dog and a monkey outside the saloon. I'm not sure if that stuff still goes on there, while you are on your bucket list trip, you may want to go thru and check it out. Beautiful country in the New Mexico mountains between Santa Fe and Albuquerque on N14 if memory serves.
Best to stay off the interstates anyways, 2 lanes is where life happens...just sayin'
