In May, 2005, PlasteredDragon hid an ammo box in Coggshall Park, Krotan's Aerie. Dozens of people each year, aided by GPS units, find the box, sign the log, exchange trinkets. It's only three-quarter miles from my house, so an easy first cache for me.

The treasure box
Coincidentally, my first stealth camping night was only yards from another geocache. I'm gonna have to go back and find that one.
