Sleeping in Airports

Thanks to JWalk, I found this link to a site showing you where you can sleep in airports.

"For travellers who are REALLY on a budget and are looking for a way to skim a few bucks off their travel expenses, why not consider sleeping in an airport? Many airports are actually better than local lodging. And to top it off - IT'S FREE! Your friends and family may look at you funny when you return with your airport stories, but that's only part of the fun."
