Some time back I stumbled upon an interesting insight on one of my blogger friends. Though its impossible to travel for FREE ! , however some of these tips might allow you to travel a lot without spending too much : Travel the world for free.
It reminds me of a typical Indian sage for whom we say :
"Ramta yogi,behta paani.... aaj yahan kal wahan !"
"It is our wits that make us men ! "
