I was a weird kid (this is harldy news I know, but even so), when I watched Star Wars back in 1978 a part of me asked very mundane questions - What WAS a moisture farmer? Were they respected? On a desert world, I guess they would have had to have been, to some extent or another. Presumably, without them, the population would die of thirst... and if so, what happened to Lars and Beru Owen's farm after their unfortunate encounter with the Empire and Luke heading offworld?
It would seem I wasn't the only one, to at least some extent.
This is from the Star Wars 10th Anniversary 3-D Special (reprinted in the Star Wars - Wild Space Omnibus, which reprints a lot of odd stuff like the UK only Star Wars stories (There are two by Alan Moore I'd have loved to post, but 1/3 of 5 pages just plain wouldn't work) and which I would thoroughly recommend getting hold of a copy of.
( Not in 3-D though... )
