The Best $5 I ever spent was to join the Days End Yahoo site. It costs $5 and you need to contact Guy to join. Once a member you get access to their list of free and inexpensive campgrounds. Simply reading the information will add to your camping pleasure. If you add sites to the really long list you can be a member for free after your first $5.
It's a really active site, I get 5 updates a day.
Simple things lige Golden Eagle provides a 50% discount at LA and TN parks are great. As well they give a list of suggested good business guys.
To join send Guy an email at GuyGipson@gmail.com
. He'll then send yu an invitation. He's an Escapee.
