This is the
Home Made Reflector Strip Cache, this isn't the first one I've found, but I do remember almost giving up on that one, I just didn't realize cache makers were so smart. This one is homemade, I see duct tape, flat magnets and reflector stuff, it doesn't matter that it's homemade, that is often the best part, that it can be made by anyone. It's also one of the few caches that are pro safety and possibly even a life saver, hopefully.
I'm not a cache, I'm just a reflector, ok I'm a cache, but I still reflect.
Oh look, duct tape, the cache makers best friend and it comes in many colors, not just gray.
Pretty shiny beehive pattern, I like it.
