Believe it or not, you can drive anywhere in the U.S. with ANY other country's driver's license, as long as it's valid. When I moved here I had almost 5 years left on my license, so I didn't bother getting a US license for a loooong time.
Bonus - apparently it's a pain in the butt for cops to write you a ticket with a foreign license, so they're more likely than average to just let you off with a warning.
