Bear_Left: All good things must come to an end, and a cache in a sign when the sign is gone is no cache at all.
For those who never found it, the Trimbles sign used to have a set of coords on it, to a ridiculous number of digits. Enough that continental drift had probably altered the last digit, let alone what the quakes might've done to it!
Thanks to the finders who wrote nice things, and to the helpful folks who replaced it and the logs a couple of times on our behalf.
