World 66 is a travel website and "sister" website to Wikitravel. So imagine Wikipedia meant for the traveler. Any place imaginable is available to be read about or edit.
A neat feature on the website is one can create maps of places visited. Above is my current states traveled to map but other ones available for customization are visited countries, visited Canadian provinces, and visited European countries.
Browse around and plan your next big or small trip today! (Hat tip: BigFlax.com Blog)
