Rochester/Marion KOA is located at the intersection of 2 busy roads. In fact part of the campground and the building with the office, showers, bathrooms, and laundry were across the road from the part of the campground we stayed at. Thank goodness we had a motorhome and were self contained.
The grounds were pretty and clean and the bathrooms and shower were clean too. But really, across the road?
