I'll have to make at least one exception to the above post and ironically it has to do with the birth town of KOA in Billings MN. Their prices are out of sight and no wonder why the local Walmart is full of overnighters, along with a security guard who leads them in for parking where he can better assist if need be during the night. Blinking amber light on his truck and all....LOL
At least this was the scenario when we stayed over in the summer of 09 and from the looks of some of the rigs, I doubt it if they were too strapped for funds. In fact, I think the main reason there are not a lot more is because it's just too hot in a lot of places and not many want to run a genset all night for the A/C's.
