Flew into Rochester on my way to the Eerie Hash House Harriers Campout Weekend and decided to take some time to benchmark and geocache during the trip. Recovered the station and both RM1 and 2. Unable to locate the azimuth mark. There are what appear to be white PVC piping as witness posts for the station and RM1. To reach, Go to Wattsburg on Highway 89 or Highway 8. Take Jamestown St., Highway 474, to the east, which turns towards the NE becoming Jamestown Rd. for about 2.9 miles. Take the dirt road north, Weeks Valley Rd., about 1.6 miles. Turn right onto dirt road, Young Rd., and go about 0.6 miles to the state line. There is a dirt turnout on the right. Station is about 100 yards to the north. From the New York side, the road is W. Gilmore Rd.
