You might enjoy Heinlein's juveniles more that "Moon". When you have time, try reading "The Rolling Stones" or "Tunnel in the Sky" or "Have Spacesuit Will Travel". They're easier to read, have fewer weird ideas, and are shorter, too.
Oh well. Back to Operation Cat Pan.
I've read some. Did read Time for the Stars and Rocketship Galileo. I liked Time for the Stars quite a bit, but didn't like the technical parts. I'm just more into everyday details, I guess.
