In the examination and dispersal of old junk department; digging up the midden; decluttering; what to keep, what to toss. An absolutely brave and praiseworthy enterprise. Endless though, innit?
The answer to some SOS or other. Must have been important at the time. Looks like California so it might have been when we ran out of gas on the second or third cross-country trip. Maps generate all kinds of memories, related or not. It wasn't when the car quit after slowly heaving its way up the Colorado Rockies. Or the alternator trouble in Alabama, forcing an overnighter. Definitely not when stuck on the muddy banks of the Tecolutla River.
Into the bin, this.
