I was introduced to D&D by my older cousin around 1982. In fact the first D&D game I was run through was when he came for my grandfathers wake. Funny that.
Then each year after ward when he would come in for Thanksgiving dinner he would run me through some sort of mini D&D mission. In fact he used the Middle-earth Quest Choose your own adventure and that pretty much got me hooked.
I went and bought the D&D basic Red Box and Blue box from Kay-Bee Toys(remember that store) at the local mall and would slowly pick up more modules from the store. I still own all of them as well and they are well worn from reading over and over again. Odd fact I still own the blue dice that you had to fill in with crayon, but they are really worn down for that plastic was a really bad compound.
Now I lived out in Farm country and had noone to play with so I ran my self through my own adventures and had a mary-jane character who was a level 15 human wizard. I don't know if I still have that character sheet ,but if I do it is well yellowed.
I would draw dungeons after dungeons ,but never actually ran anyone through them, thank god. They were a nightmare of design, mounty- hauls and every dungeon ended with a dragon. How orginal.
