You'll notice a fairly obvious moat that you need not cross at this cache site, at least if you attempt it from the parking coordinates provided below. During the summer the moat may dry up, but on the day the cache was hidden it was quite obvious and treacherous to cross.
You could access the cache from the trail on the opposite side of the moat if you continue to follow the trail past Quinsigamond Cache, but note the cache was hidden via the gas line trail access, so not sure how good the other trail would be. \
The cache itself is a small camoed screwtop container. Please rehide well and hope you enjoy.
