Has anyone heard of this? I recently came across it while reading an article in the NY Times and thought I'd check it out. Looks like it could be quite interesting! I'm usually pretty open to taking people in,,,my family always had waifs & strays coming by, some we knew, some we didn't. I realise that caution is needed, but the site answers alot of questions concerning safety, etc., but overall it looks like it could be good fun....and maybe cheapo holidays!
