this guy probably doesn't know what he's talking about but you can, in fact, travel without money. just not very far, very fast, or to a guaranteed location. i hitchhiked all around europe during my studies on semester breaks when i had lot of time and no money... i slept under bridges in a cheap sleeping bag or under a tarp on an alpine meadows and ate the cheapest grocery store items that didn't need cooking. i typically spent less while traveling than i would have spent if i stayed home (especially if i didn't need to pay rent during the summer).
