That's merely the danger of having a computer generate your instructions. I've used Google Maps to drive a lot of different cities in the US. Sometimes those details are critical, sometimes they're not. Unless a human being reviews each result, I doubt they'll even be 100% perfect. Speaking of which, you should see the trouble Google Maps street view has dealing with roads around downtown Boston. It obviously hasn't been fully tested with 3-D roads stacked 5 deep above and below ground. -- "XML is like violence: if it doesn't solve your problem, you aren't using enough of it." - Chris Maden -------------------- BYU Unix Users Group http://uug.byu.edu/ The opinions expressed in this message are the responsibility of their author.
