I know exactly where this is. This is the 'ye Olde Robbins burial place' it's in Cream Ridge NJ near the Horse Park of New Jersey.

My grandparents lived right down the road and I spent A LOT of time exploring it as a kid. That grave in the foreground with the metal fence thing around it is Abraham Lincoln's neice. I believe her name was Sarah.

Be careful where you tread off-trail. There are at least a dozen or so graves that are only marked by chunks of stone with crude initials. They are sometimes buried under the leaves and suck to trip on.

There is also a cool old path (I assume the original path) that is lined with chunks of sandstone. The same kind of chunks as the crude initial graves.

Some of the family names in that plot are the namesakes of many local towns/roads. I forget all the details, though.

When I was a kid (the 90s) fresh flags and plastic flowers would still show up on special occasions.

Wow. Never thought I'd see my secret childhood hideaway spot on reddit.
