This may not be good news for full timers

I have posted on here before and will now. I have seen no empty sales lots. There are 2 local between Asheboro, NC and Apex, NC that are running over with inventory. Up above Richmond, VA on I 95 they are chuck full on both sides of the road. I have been all over the South East from PA to FL and only once saw a park full, once. That was on I-81 in Winchester, VA. I was in TN over the 4th and stayed in 2 different campgrounds without reservations. Called in the morning to stay that night one in Bristol and one in Pigeon Forge.
I keep reading these doom and gloom posts but I just don,t see it. Heading out in the morning and have no reservations!
