We are currently in Lincoln City, OR for a month. We made reservations six months ago but had to split the month between three different sites to get it all. A couple pulled in next to us last night wanting to stay two nights but only one night was available. They called another place up the coast and got their last site for tonight. Of course this is the busy time of the year but we have noted many more RVs on the road this year. The campground we are in fills up every night - 80 sites. Unless things change, I think many who like to free-wheel without reservations are going to have to take what's left in an area.
