Speaking of which, this is a magnetic, micro-sized cache on a guardrail.
People geocache for different reasons, and cachers have different goals. One common goal is for a cacher to try to fill all 366 days of their geocaching calendar. But Metro East has somewhat fewer caches than the rest of St Louis, and some cachers on this side of the river have cleaned them out, making it harder to fill their calendar. So I put out this cache as a "public service" ;) for those folks who need to fill a day on their calendar.
This is a simple PNG (please park and retrieve safely), with no frills or twists. Enjoy!
