Not just Oregon, though we did run into minor availability problems this spring with loops still being closed & there was demand for them to be open.
My guess is that it is the difference between a privately run CG which has to make a profit & a state run CG which does not. The motivation to get every camper possible is not there.
Had a similar problem with a MD SP last fall. They shut it down because work was being done on the bathroom. No big deal to us. We are self contained. We seldom us a CG bathroom for anything. Don't require water at the site either.
All we really want is power when it is extra cold or hot. Nope. Park closed.
Leaves you scratching your head sometimes.
