Lets see, Earliest memory of reading.... so that's not going to count my mother telling me to avoid it, it's evil.
So in 7th grade I had read a magazine article about the Minotaur and Labyrinth legend, and the article had art of a maze from above. It was a terrible maze, lots of chambers that were impossible to get into, really easy to solve, etc. So one day in class some guys saw me drawing a maze. They complimented it, And they asked if it was for D&D, I told them no, it's just to make a maze. They then loaded me a Forgotten Realms boxed set, I poured over every word of that loving it! Didn't play for almost a decade later though.
