Great paved rails to trails route for walking, biking or exercising the dog on leash. Suitable for strollers, too, but be aware that the cache is about 15 feet or so off trail.
Cache container screws open from the left. Be sure to wedge the inner container so the cache can be screwed back together.
Bonus points if you know what this is for.
Congratulations to Elwood1 for his FTF.
