Re: Say you have $15,000 and want to travel for awhile
if you do it right you can see a good chunk of the world on $15k.
I'd start by getting a duffle bag from an army supply store and then just wearing jeans, tshirts, my old sneakers (for when I'm in other countries, dont want to give a vibe of money/worth) then renting a cheap hatchback and drive it around the country. just grab a sleeping bag from walmart and sleep in the car and use laundry mats for clothes and KOA's/truckstops for showers.
after that, head to the border and start seeing south america. once I get over seeing that, I'd head to the nearest international airport and get the cheapest plane ticket to europe. go all over europe using their rail system, boat system, etc. Then end up in hong kong and hope I dont disappear and then hit up japan and use its rail system to get around.
If there's any cash left I'd try hitting up australia but only one of the major cities, probably sidney. then if there's any cash left, I might try island hopping or just head home.
