This cache is part of my Sandwich, MA series of caches that make up my Girl Scout Gold Award project. Easy to find near a sign in the parking lot median and accessible when the museum is not open, this cache is labeled unknown because it is a plant stake with a QR code. Download the i-inigma QR code reading app to your smartphone (free for both Android and iPhone) to scan the QR code for information on the cache location.
To log this cache, you must use a password. The password can be found by scanning the QR code on the plant stake.
