Travel discounts, freebies

"The Mature Traveler's Book of Deals" by Gene and Adele Malott (GEM Publishing Group) can tell you where you can travel for free. Of course, it may involve being a volunteer at a state park in Georgia or being a tour group leader. But this book has great ideas on how to travel for nothing or for a minimal price, as well as information about cut-rate auto rentals, cruise discounts, other money-savers and, more importantly, tips on how to find them.
