It has been getting harder to get into campgrounds for the last 5 years for us weekend warriors with kids.
My youngest starts college in August, and we are working from home, so we are hoping to be able to work from the beach for a week or two this fall.
Here in the southeast, the State Parks and COE campgrounds on the lake or beach stay booked on the weekends almost a year in advance. I know a few people that will grab a site for every weekend of the summer, then cancel the ones they don't want at the cancelation deadline.
