"Superman: Up, Up, and Away" was one of the first three trades I bought. (It was a three-for-two sale, I got "Superman: Strange Attractors" and the second Superbuddies trade as well.) I've been meaning to re-read it, but I can't find it in my incredibly messy and disorganized room. ARRGH.
Love the writing, love the art, love Lois and Clark. And I love the fact that Lois has to watch him get dressed. Heh.
One thing I thought was odd about OYL, was that in the Superman books the only person who mentioned Kon and his death was Lex flippin' Luthor. I'm sure Clark dealt with it over OYL, but it's something I would have liked to see.
