If you are around the area, there is no excuse to not make some time to attend one of these. The Fermilab's series of physics talks for the public is back.
So even when the Tevatron is gone, the lab isn't dead. But more importantly, they are continuing their effort on public education. This is the opportunity not only to listen to some of the best people around talking on a particular topic, but also to interact with scientists working there.
At least this isn't a dance performance depicting, say, Project X! :)
