In the Park's heyday, Cobblestone Village was filled with gift shoppes, food concessions and a "Broadway" stage. But as attendance fell off, more and more of them were shuttered. Some were repurposed as offices or used for storage and some, well, some were used for other purposes.
The Park was located in Sussex County, a red pocket of an otherwise Blue State, and as such, there was a certain, uh, disregard, for the federal government and their pesky rules. So it shouldn't have come as a surprise that one night, during a routine sweep of the area, security found a functioning still in one of the vacant shoppes.
Moonshine. Apparently, it's making a comeback.
