RTW trip through US, Canada, central and south America, and europe anyone??

Hey all!!
I'm planning a RTW trip starting in September 2008 for a year. I want to see US, central and south America, Europe, and western Canada. This trip will be done on a tight budget (camping, buses, hostels) but I don't really have a set itinerary and I would be willing to change it if someone has a similar plan. All I really know is that I want to experience the great outdoors and all of the interesting cultures. I'm a 19 y/o university student taking a year off. If anyone (close to my age) is up for a trip like this or if you have similar plans let me know. Thanks!

Around how much are you willing to take with you and how much will it cost around
thx mick 18 going on 19 july

Hi Mick
I am only taking with me what I can carry on my back. I'll be on a tight budget for one year (with a couple of flights in there) so hopefully it won't cost more than 8 or 9 thousand, but that a very rough estimate. Where you planning a similar trip?

Hi I'd love to travel the world but I was thinking the other way. Like Australia to Sotheast Asia then to Europe. I do know some people in other countries and I did live in Australia for four months before. I'm 22 and a college graduate on a budget as well. Let me know!
