I remember all that hantavirus stuff! We were there in '89. It has been WAY too long since ... I would love to go back.
Oh, how nice you had the Four Corners to yourselves! There were deer all over the place at Mesa Verde!
Not to mention the omnipresent turkey vulture!
You were luck you got to enjoy the camping aspect of things. I'm a bit too "soft" to do that, so always stayed at motels or lodges. Given, too, that that was the first year of the Clintoon escapades, and I was following his moves like a hawk every day, I was horrified to arrive at the lodge in Mesa Verde to discover there was no tv ! :-P
The real difficulty I had at MV was climbing up and down the ladders, not for any other reason than because of my unusually large feet. The Anasazi sure had dainty little feet !
