Hey everyone, you seem to be more experienced than me! Me and 2 friends are going travelling in 2009 around South America, but we want to see some of the US too and end up in New York before flying home. We were thinking of flying from Peru to Mexico, exploring there for a bit then travelling up to NY. We will all be 19 whilst travelling, so the cost of renting a car will probably be too high for us, plus we have absolutely no experience and we've all only been to America a few times! So...how do you recommend that we travel, and which cities/places along the way are a must to visit? Obviously we will be doing our own research and planning the trip according to our own personal ideas of how we want to do it..but your advice would be greatly appreciated!
