As you may have noticed, the economy has not been doing too well. There are a lot of people that have lost their homes and living in an RV in an motor home/trailer is all that they have. On the flip side, if it weren't for them, most of those same RV Parks would be closed and we would not even have the opportunity to stay there.
I have stayed at RV parks that had so many full timers that the school bus actually stopped there.
To me it doesn't matter since I only stay a night or two and I am just thankful that I have the means to travel around while others are doing everything they can to keep their family together.
