Try searching for the Salida Chamber of Commerce or perhaps Visitors Bureau for places to stay. You should be able to find this nice little RV park just downstream of Salida that looks like a nice place to stay/camp and they have all the stuff that a KOA would have but it looks nicer than any KOA that I have been to. Sorry, I dont have the name of the place but it is right on the Ark river.
There is also a campground on Chalk Creek (close to the ARK) at Nathrop. It used to be called Browns Campground or something like that but they changed ownership and names so I cant help much on that either. You could call CKS and ask them what the new name is. CKS was located right across the road from them before CKS moved to BV.
I know where they are but just dont know the names of the places but with some homework, you can find them. If the ladies like showers, they will no doubt like these 2 places.
You will probably be running Fractions, Frog Rock, BV Town Run and Brown's Canyon most the time and those places would put you fairly close to that action - Nathrop would be closer than Salida. If you wanted to do Parkdale downstream, it's only about a 40 minute drive down from Salida. Take your pick.
