More people should want to do this! Don’t you agree, Nellysam? :P I found out about it with the book, The Lonely Planet Guide to Experimental Travel. It consists of a bunch of silly games to play to explore the world around you in a different way. Experiments: http://www.lonelyplanet.com/experimentaltravel/contents.cfm
And I have another experiment idea. Take an old guidebook for the place you’re going to. The older, the more irrelevant it will be. See how many of the sites are the same, or even still there. It would be interesting.
