I have not been to Silverwood up by Coeur d'Alene (Northwests largest amusement park) but have heard from people in Boise who have traveled up there that the rollercoasters are rather impressive for a smaller park. I'm not sure of the size comparison of Silverwood compared to Lagoon or Elitch, but their website lists over 65 rides (Lagoons mentions over 45) along with the largest water park in the NW. Pretty cool considering this park first opened in 1988.
