This little program called Google City Tours is kinda neat for those of us who want to hit the high points and avoid all that tiring research. Just type in the name of a place, click, and presto! you've got a little walking tour mapped out, complete with suggested time to spend at the attraction site and the travel time (on foot) to get there. Be advised, though, Google CT is picky about the cities it will tour in. Oklahoma City and Norman didn't rate in OK, and Baton Rouge didn't make it in Louisiana. But Cairo works, and Portland OR, and New Orleans, and Dallas+Ft Worth and Cleveland, and Mainz, Germany, and St Petersburg, Russia, and finally, Basel, Switzerland. I wore out about 15 minutes just playing around at these places.
Finally, let me suggest you take a look at "Google Reader - Play," that's what they call it. It's just a place that throws a potpourri of various stories at you, somewhat like their Fast Flip, only my little test, hardly scientific, I thought the stories on the former were more interesting and catchy, but that's only a matter of opinion.
Have fun, y'all!
