Finding a taxi in a large city can sometimes be as difficult as finding a needle in a haystack. Then again, there are usually very few haystacks in the city, and besides, why do people put needles in them anyway?
Google recently launched Ride Finder, which is a simple way to find a taxi in 10 of the largest U.S. cities (sorry L.A., Seattle and Las Vegas ... surely you'll be on Ride Finder soon).
Once you select a city, you'll be able to view all available taxis (at least, the ones Google has in its system). Then you can update their locations as often as you'd like. This morning, though, it doesn't look like the St. Louis taxis are moving very far. Maybe another site has started a hitchhiking service instead.
