A few weeks ago I was going through a bunch of AD&D modules to see if any would convert well for our new 5e campaign. I opened up C2, the Castle of Inverness and found handwritten notes by my best friend who got us into the game and always DMd for us. He had added a bunch of traps in the unoccupied rooms and some made up magic items that would be specific finds for the characters we were playing at the time. (Halfling thief for me). We never got to it in that campaign and he passed away a couple of years later at 22 - some 25 years ago now. I don't have anything quite as significant as that. Quite a few all nighters were pulled during that time.
