lol...wanna make the question more specific?...
do u mean to volunteer, go backpacking, trekking, sightseeing, clubbing....???

Back to the States then work my way down along a certain highway- can't remember the name now- which takes you through Mexico, down into the rest of Central America and into the South, then down to the tip of South America and back around to Brazil. Then back to the States via some of the Carribean, just for the sake of it really. I've already planned the route and researched a lot into it, just need a year or so of my life and the money. I'd do some sort of volunteer work along the way, as I speak Spanish pretty well and already have links to charites over there.

Or alternativley, I'd go back to Mongolia, then down to China and attempt to get into Tibet either from the Chinese side, or go around into Nepal and go that way. Then back around into the Central Asian countries such as Kazakstan, Uzbekistan etc. Got a vauge plan for that one too, but I've already spent a fair amount of time in Asia whereas I've only been in Central America for a couple of months. I kind of just wanna go and live in Mongolia for awhile. I speak some Mongolian from this summer, and am learning it now so it'd be good to get it properly learnt as its unique, and cool, language to have.

I am on a gap year, and im going to do europe and asia

America ive been before but i want to spend ages there and see everything.

Also Ireland bizzarely
