Marcy Correctional Facility is a medium-security state prison for males in Marcy, Oneida County, New York. Marcy specializes in providing alcohol and drug treatment programs. All of Marcy is on one level; there are no stairs, making it especially suitable for disabled prisoners.
In 2003-2005, they built the $33 million Judd Road Expressway which extended NY 8 north from a cloverleaf to a commercial district off of NY 5B.
While I doubt it's a one-horse town along US 20, it certainly is not a big and prestigous city in Oneida County. More like a speed trap, but at least it's well marked and just one stoplight before your beyond it.
Great fun but as you can see towards the top I lost the trail and ended up searching for it for a bit.
