Wow, just realized that this month marks 38 years since I graduated high school....
I started playing D&D 6 years before that, so 44 years of D&D and I still can't get enough.
I started roll playing in the early 70s which was very different than Gary Gygax's D&D. We convened in the Arkansas State Beebe Student Union when we had the time and picked miniatures from whatever was available. The rules were typed on letter paper and were mimeograph or Xerox copies.
