Maybe you've had a few such moments during your Geocaching adventures.
You can find this cache easily enough, but for big cacher-kudos, please share your own Geocaching "Here's Your Sign!" experience, whether about yourself, a fellow Geocacher (be nice) or an anonymous muggle. While you may flourish a bit on the punch-line, the core of the experience must remain truthful!
Not sure what a "Here's Your Sign!" joke is like? A quick internet search should dispel the mystery. But here's one of my own:
"I was participating in a CITO event in Houston's Armand Bayou via a tandem kayak shared with BaytownBert in November of 2013. As we picked up trash floating in the bayou, we spotted the heads dozens of alligators, but most sank below the surface before we got close enough to them for a good picture. However, one little gator floated lazily on a submerged bed of tall grass along the water's edge, not paying us any mind while soaking up the sun, so we drifted in close for a better look. Only a few feet away now, I reached for my camera. BaytownBert asked me, "Are you gonna take a picture of him?" To which I replied, "No, I was gonna place a cache in him!" Here's your sign!"
Congratulations to Walkoff Worden for the FTF!
