I've just recently become aware of a new feature from the Travel section of the New York Times online. The Frugal Traveler, Matt Gross, is traveling across Europe for twelve weeks this summer on a 100 euro a day budget.
This seems like exactly the type of thing I would love to do, and it's all really interesting. Gross goes around with a video camera and films about five minute videos once a week. So far he's been to Calais, France, Paris, and WWOOF'd on a farm in southern France.
It looks like Gross has done this before, apparently driving across the U.S. on $100 a day last summer. That'd definitely be tough to do now, however, with the gas prices the way they are. You should take a look at the Frugal Traveler page and see what he's up to and how he's working on multimedia packages while overseas.
