At Point of Pines, Arizona, with legendary archaeologist Emil Haury.  I know I look like I am really pissed at him but I wasn't, I was just trying really hard to concentrate on his rap.  He was a very smart man but from a whole different intellectual era, and he would try to suck you into his way of thinking about things, and you had to use all your mental powers to resist, which caused the eyebrows to scrunch.
