Northampton - Hamlin Beach
The only thing that keeps you from going any further north on this ride is Lake Ontario. Hamlin Beach park has concession stands with the usual "park fare" and there is a camp store in the camping area, so you might want to take a lunch for this 51 mile ride. The only place for food other than the park, is Holley, which is almost back at the start. Assuming this will be ridden in the summer, you may want to go for a dip in the lake to cool off before heading back. These roads are lightly traveled and very flat.
