I am pretty new to camping, but a friend recently told me about Passport America - 50% Discount Camping club. I was interested so I called them up and spoke to a salesperson at length. She persuaded me to join. I received their package (i.e. Directory, Membership card, membership letter, decals, brochures). I have to say that what I see is pretty impressive. I was skeptical at first, but its working. I have already saved money. I paid $44.00 for a one year membership and I have saved over $100.00 just from staying at a few parks. They have a wonderful and very informative website (www.CampSave50percent.com). They also have this referral program where I can even make money by telling people about Passport America! If anyone here has any questions or comments, I will be glad to answer and maybe help.
