Rejoice ye homeshoppers: A handy new Web site makes it easy to plot the most efficient way to hit six open houses on a Sunday afternoon. Simply input as many addresses as you like, and the site produces a Google map with a suggested itinerary, and a complete set of directions.

The aptly named IdealRoute is hosted by the Virginia Association of Realtors, but it works for addresses anywhere in the United States. (In fact, it also works for addresses in Canada, and quite possibly elsewhere too.) The site is billed for use by real estate agents, but it's yet another example of how the Web can make it easier to shop for homes on your own.

Pictured is an itinerary for visiting several Boston branch libraries.

(A tip of the hat to the Inman News Blog, where I first read about the site.)
