Brian May, Guitarist for Queen. Shook his hand, talked to him, got an autograph. I'm a huge Queen fan for over 30 years, so this was incredible for me. He is also a Doctor of Astrophysics. I met him at the Griffith Park Observatory in Los Angeles. Sadly, they were very restrictive on camera use--no flash photography except for a brief moment when he was introduced. Before the show, he walked right past me, and I rushed to get my camera for a photo--it came out blurry.
