We have stayed here
http://koa.com/campgrounds/herkimer/ on 3 diff trips we go the the Pro motocross races up in UNADILLA MX New Berlin, NY and the track is only like 20 min ride to Cooperstown NY.
The campground is maybe 40 or so min drive to Cooperstown NY
We take a back rode and can see the farms and the sites.
We always get a pull into site nice and clean and well ran place.
Will be going back this year to.
The back road we take has one steep hill it has a run off for truckers if there breaks heat up and can not stop.
It has signs posted befor you get to it just make sure you build up speed to get over it. The 1st time I did not and was praying that the dodge was going to make it.
