Today was the last day of the particle astrophysics conference.

The morning was spent discussing the future of WIPP as a facility for low-background radiation physics experiments. It sounds like there's a lot of strong interest in making this happen, which is a Really Good Thing for the future of particle astrophysics in America.

The afternoon was spent on a tour of the WIPP underground and waste handling facility. I wrote about this tour the last time I took it. This time, it was basically the same except there were more tourists and we didn't get to see drilling in progress. I did, however, get to look at Ernst's neutrino experiment, which was very exciting.

Did you all go out and celebrate Flag Day today? I know I did... I took two of the free flags they were giving away at lunch and stuck them in my bandana.

Once, on Arbor Day, I tried to put an entire tree in my bandana. It really hurt.
