Purina Towers are just on the outskirts of Dunkirk. As you look at Dunkirk from the water from the water it's on the left. There are two cement towers. One has the Purina symbol ( red and white checks ) on it. I guess you would say east of the city pier. Center Rd. is further east of Dunkirk towards Cattaraugus Creek. Probably half ways. From the lake Center Road looks like a definate cut in the trees from Rt 5 right up to the top of the hill.
