This is hidden in a traditional Maine Rose Series - fashion, which should be easy to find with the coords. Do watch carefully for traffic and pull well off the road but do not block the private drive.
Once you find the cache, proceed on down the road and find another cache (Kan Koozie Kache - GC153RZ) or bring your favorite youth, 15 and under for fishing in the private pond (regulated under IF&W law)! The grounds between the road and the Penobscot River are private but public is allowed to enjoy the trails. CITO please and observe the posted rules for dogs.
A bit of stealth might be advisable given the location.
