I'm from Oregon and yeah it's amazing how many are still booked up. Some of that though has to do with the State parks themselves. Many will close certain loops because they don't fill up and it's less maintenance to do.
Two weeks ago we stayed at Bend Sisters Garden RV park. It was all but full. Last weekend we stayed at Armitage Park in Eugene and it was full.
You can get into some of the coast St parks. South Beach is usually a good option. Beverly Beach tends to stay full longer.
I think it's a combination of brisk RV sales and warmer weather lasting longer into the season.
