The cache is not at the posted coordinates. It's at: N39 52.XXX W075 00.YYY Solve for XXX & YYY and find the cache.
Finding 5,000 caches isn't something that is very common. In North America (actually just the USA), only about 3,735 cachers have met this goal. In the World, only about 8,420 cachers have done it.
There's an unactivated TB for the FTF. Congratulations to Foundinnj for being FTF!
