Much earlier in the semester Dave called home one late morning to tell me he was coming to get us so Dietrich could see this military helicopter. I don't recall why the helicopter stopped at the campus, but it was there for some time and his entire class (graduate students mind you) were outside taking pictures. So was their teacher of course. I thought it was kind of funny. Dietrich and I didn't see it land, but we did see it take off. Whoa, what a wind! It was a fun little outing for the day.
