This is no longer Salem KOA, it seems it has been sold and renamed Happy Valley RV Park. There's no web site yet, but there is some construction going on for a new section and it seems the place is being fixed up.
Very clean and well taken care of. The site we stayed in was a 70 foot long pull through with plenty of space for opposite-side slide outs (2 cars + small enclosed trailer + tow dolly + RV fit with plenty of room). There were several monthly sites, no run-down RVs in the park. Internet speed was reasonable, and only slowed once in a great while during peak hours. We would definitely stay here again
