That is awesome man. I too go out there from time to time to see if I can find family artifacts, but I've not found any. Very cool that ya'll found that card, preserving it for the family.
Yes, That is what everybody called him from the time I can remember. It fit him to a T in todays connotation but I'm pretty sure that it was a life long thing, way before chill was cool. My brother who found the card and I have been trying to reach out to the few people that are still living that knew him but no luck so far.Did he sign 'Chill' ? Great nickname if so.
