This cache is located on the Black trail. The Doctor is believed to be the last of the Time Lords, a race of aliens who travel through time and space. The Doctor was key in the Time War with the Daleks and was forced to make a decision no one should ever have to. To save the universe, he caused the destruction of the Dalek race, the Time Lord race, and his home planet of Gallifrey...or so he thought. Through his power of regeneration, the Doctor changes appearance when he "dies." The Doctor takes on companions to help him in his battles to keep the universe safe as rifts in the space/time fabric threaten to destroy it. The Vassar Farm property is open from sunrise to sunset. Coordinates for parking and trailheads can be found on GC54JTT (Little Blue Box) Dogs are allowed and must be leashed. There is a trail map on a kiosk as the main parking area or on their web site at http://farm.vassar.edu/map/ Bikes are allowed, but NOT on the Dark Blue, Green, or Black trails. I wouldn't recommend the use of bikes on the Yellow or Red trails either unless you consider yourself an excellent rider.
