Cachin': Impuggible Mystery Cache

This is a three-stage cache.  YOU MUST bring two AA batteries to complete stage one.  For those of you using a hand held GPS instead of a phone app, simply take the batteries out of your GPS and use them to complete the task. IMPORTANT: The device at stage one is old, but you will recognize it when you see it. Hold the button down to get the device to work. If you just try to click it into place, it may not work properly. EDIT: This device may or may not work, depending on the weather. You may want to bring a cassette player with you to properly finish stage one.
