Im pretty sure thats not the right cemetery. There are a few in Troy, thats not the one Uncle Sam is buried in. Thats right off Hoosic St, about 2m or so off to the left. Been there numerous times, pretty cool/creepy place.
Oakwood is more through the city, and tougher to find. The 1 time we went there we got hasseled by the cops and almost arrested! lol
