I remember there being a cache here at some point in the past and thought it would be a good place for some new ones! At the posted coords you'll find the gears used in the original drawbridge. Pretty cool! In addition you'll find six plaques that you'll need to get some information from to get the coords to the final. To find this cache you'll need to use the two Penns Neck Bridge History plaques.
The final can be found at N39 34.ABC W75 28.DEF
