G'day!

Me and a pal or two are in the early stages of planning a huge trip at the end of '08 through '09 for a year.

We're going to be working in Canada for a few months hopefully then end up near Niagara Falls and head into the US.
From there we want to head down the country to Florida.
From there we will end up heading accross the country to California.
Eventually we will head down to Mexico etc.

but i just have a few questions about the US section of our journey and your thoughts on the best and cheapest way to do this?

we dont really have any plans on which states to visit but just want to spend a few months exploring your country.

I guess the best way for us to do it would be to buy a car? and camp as much as we can to keep the costs down?

basically id just like some of your thoughts and suggestions?
Thanks very much, looking forward to hearing them and some of your stories :)
