In order to keep my curvy, svelte figure, I've taken to biking around my adopted hometown of Pittsfield. As I've pedaled along, one thing I noticed is that there are a lot of long stretches of road in this town with lonely guardrails yearning to host little magnetic containers. Most gz's will have room to pull your car over off the road. For those caches that don't have that extra room, please take care exiting your car. As I continue my trips around town and discover more gr's, I'll add to the series.
Congrats to Maine to Massachusetts for being first to find.
