A stone's throw away from Arlington Center, and a quick hop from Spy Pond Park. I've walked and biked along this stretch of the Minuteman Bikeway more times than I can count. I've seen art installations, the local chickens, and all manner of passersby. The abutting Spy Pond Field is host to baseball games, frisbee, soccer, tennis, and all manner of recreation.
My daughter and I placed this cache together. No hint (at least for now) to make it just a bit more challenging. Signal can be a bit bouncy because of the hill - use your geosense! Hope you enjoy the area!
Congrats to FlatteredCrab on the FTF!
