Camping is a fun, inexpensive way to spend time with your family, at least that’s what it used to be. Now after the initial investment of equipment, you still have steep reservation fees and park entrance fees that make your cheap fun a little less reasonable.  Here’s a nice little tool to help you find free places to camp throughout the United States.  FreeCampgrounds help users find places where campers or RVers are welcome to legally stay a night for free, or for less than $10. Find the best free or low-cost camping opportunities where you’re headed.
