Well, now I can really kick myself. I knew where he lived. I bought some stuff off him a few years back.
Tried to locate his house a couple times last month, and failed, but never went to the trouble of looking up
his address in my archives :(
MS affected his motor skills, but never affected his mind. Not sure what did affect his mind :)
He was sharp, mentally, but pretty much in an alternate reality when it came to a lot of subjects.
