I noted last month that Google Maps now supports Multiple Destinations.
On Safari on my old Powerbook 12″ 1 ghz, the “Add Destination” feature is very slooooowww and thus I didn’t use it much. Today I realized that the destination point allowed a simple command to enter all of your travel points at once. In the destination field simply enter “City, St. to:City, St to:Next City, St.” etc. and the complete route may be entered very quickly.
