I like to listen to the "Political Junkie" radio show on NPR every Wednesday. The introduction to the show features a bunch of famous & infamous statements, like "you won't have Nixon to kick around any more," and Howard Dean's scream. Barry Goldwater's contribution is "extremism in the defense of liberty is no vice." I hear it every week and find it chilling every time.
Goldwater was a fine photographer and used the resources of his native state to get some good stuff. As for the other thing, there's something new I never heard before -- "photobomb." It is, I guess, when somebody does somehting wild and crazy and photogs get in in their camera. I don't like the term but I guess I'm an old grouch.
