Last Friday, we opened up the old observatory for an open house. Despite the clouds, we had a few busses of high school students to entertain. The physics undergrads did a large amount of entertaining. I gave one talk, then we went to see if anyone wanted a second round of it an hour later, and the physics students were showing some high schoolers momentum and energy transfer. With a hammer.
The downside was that I was back nearly at midnight. It's a good 45 minute drive to the old observatory, the last 2 miles on dirt roads across fields and pastures. At least I arrived at twilight, when you can see the signs. And the roads had dried out enough from the rain we've been getting.
