My name is Jessica and I'm from Stockholm. A friend and I are travelling the world starting in January and Thailand. The 20th of April we'll be arriving in Los Angeles. Unfortunately none of us have a drivers license, but perhaps a kind soul or two are going on a road trip up the Californian coast or to Las Vegas and we could tag along. We'll pay for gas money and you'll be in really good company.
April is a long way off. Contact me a week before you hit the US and I might be able to help. I can certainly help if you make it to Vegas. Good luck with your adventure!
Jessica - please be extra cautious about who you and friend ride with! The USA is considerably more dangerous than Sweden, and the internet is not a really good place to ask for a ride (almost like e-hitching).

Although Mike @ #2 is of course a fabulous guy and you couldn't do any better than hooking up with him.
