For those traveling in or thru Texas,
Texascampgrounds.com should be a useful tool for locating an RV park in an area you are headed. You can select a town/city name and search for all RV parks within X miles of that town/city. Unlike campgroundreviews.com where it will only list RV parks within the immediate area of the city selected.
For example, campgroundreviews.com does not even list Dallas. But using the above link you can find parks within however many miles you may be interested in staying. It will list the parks and the mileage. Not that Dallas is a typical RV destination, just an example.
Then you can use campgroundreviews.com to see user ratings for any you may be interested in.
I just received the magazine and did not realize there were so many RV parks around the area I live in.
