I lived two blocks from his house from 85-89. TSR still had some licensed production locally and dumpster diving was encouraged, so there are plenty of cool pieces in local collections.
The culture ran pretty deep, several of my friend's parents were involved in some way or another. My best friend lived even closer to the D&D house and his mother was one of the main authors of the "Choose Your Own Adventure" books.
You can still find locals with wild stories that would be great parables for a new religion dedicated to table games and debauchery.
