Plummer (Silver Street) Cemetery, Milton, NH
My recollection of the exact location of this cemetery is vague, but a MapQuest search for Silver Street in Milton should put you in the ballpark. I do remember having to trek through some heavy underbrush behind a private residence to get there, but it's possible I entered from the wrong direction. Regardless, this small cemetery is quite well maintained, and most of the stones are legible and in relatively good condition.
The photo gallery requires at least Flash version 9.0.28.
