Welcome to the Area 51 Cache Series. There is a highly classified American Air Force Base located in Nevada called Area 51. Rumors spread that alien knowledge is gained at this base, however confirmation is yet to be achieved.
51 caches on RDR's reminded the original CO of the American Area 51 and this series was born. Be safe out there.
All caches are located on RDR's that probably won't be plowed in the winter but would make a great ski or snowshoe hike. And there will be mud in the spring.
All caches are small and winter friendly and shouldn't require a long bushwack. ( Except # 11 which is a bit longer ) Have fun.
