Oregon/Washington - May or September?

The weather was awful but that is what you get in that part of the world.

Awful is as good as it gets, stay home, It rains every day, some times it has ice in it. Camp grounds are always expensive and full of mean people.
Come to Wa. Keep Wa green, bring money.

Like em or not, you will need reservations during either of those months if you can get them. If the time period you select is first come, first serve then you will have a lot of competition. You may end up doing a lot of searching for a place to stay.
At this point it will be very hard to get them though. Our state parks take resi's 9 mos in advance and almost everything for the summer is booked by now. If you keep checking, you may get in someplace.

We live here and camp here a lot. We like left overs when eating....but not so much when camping.

We have our favorite campgrounds and favorite sites in them. Without reservations in May or September we end up with left overs.

But, Oregon and Washington are a must destination for any serious RVer, so don't let any of this discourage you.
