Yet another quick P&G on a quiet back country road.
An American Buffalo.
Be sure to bring something to sign the log. The cache is too small to contain one. Geocaching guidelines state for physical caches other than challenge caches, any additional logging requirement beyond finding the cache and signing the log must be optional. Caches can be logged online as "Found" after the geocacher has visited the coordinates and signed the log. Your log will be deleted if you did not sign the log.
