How it spread
Trace the originDave Ulmer posted a hidden bucket’s coordinates to a GPS newsgroup. Other readers found it and hid their own caches. A shared directory and later news coverage helped the activity escape its original technical audience.
Documented milestone; not a measured attention peak.
