It seemed like a year ago we could plan trips from one month to the next. Now, if we don't book a site at least 6 months in advance, we either can't get a site, or cannot get the site we would like. We have 2 trips to WV coming in April and June. I had to book those both last March. for the June trip, we booked the last 2 sites available more than a year in advance!
Hoping things would get better with Covid calming down now and diesel getting more and more expensive. We haven't seen a change yet, though.
