My first astronaut signature 

NASA astronaut Doug Wheelock is signing my NASATweetup STS-135 T-shirt. It was my first astronaut autograph of the Tweetup. I love that we're both sporting big grins. (And yes, Wheelock was a favorite with some of the ladies at the Tweetup, albeit there was one gal who was apparently more into Elmo. She asked a zinger of a question: Did Elmo know what a cougar is? lol)
