Being fairly new to the RV thing, last summer I reserved campsites well in advance (a month or so) so I would have one less thing to worry about while on the road. I just started looking for this summer and was surprised to find that virtually all the WA State Parks I checked (about 10) were booked solid every weekend until late September. An occassional weekday was available but not many. My questions...is it now necessary to book a year or more in advance to get campsites? What is it like in your state? Many thanks! Have an awesome summer!
