Summer is the traveling season, and this new site from National Geographic may well come in handy. The site offers informative briefs on a number of popular tourist destinations in the US and Canada, including national parks and major cities. These are selected via geographic pull-down menus or alphabetical/ state listings. Each guide offers an overview of the park or city, highlights, driving tours, bird-watching tips, nearby attractions, the best time to go, lodging and travel tips, and statistics, among other information. At present the Destination Guide covers about 30 spots, but more will be added on a continual basis.
