And you can freeze your tail off climbing up and down the paths in beautiful Carlsbad Cavern in southeastern New Mexico. That's the most beautiful cave I know of in the U.S., and I've taken the tour through several others.
And there's Los Alamos, atomic city, and the museum about the Manhattan Project is great.
And I could go on and on, because New Mexico is loaded with fascinating sights, and the New Mexican style of Mexican food beats all others, IMHO.
I also want to go to the Carlsbad Caverns. I have been to the Luray Carverns in Virginia, but I've never been to Carlsbad.
Hundreds of thousands of Mexican free-tailed bats, whirling counterclockwise, spill forth from a gigantic hole in the earth and are silhouetted against a colorful desert sky...this is the bat flight experience at Carlsbad Caverns National Park.
