Gas up

It's practically summer, which means it's time to partake in that classic ritual: the great American road trip. Don't know where to go or how to get there? The mystery's part of the fun, but those who need a little direction can find it at the Roadtrippers website. This free-membership site helps users plan trips with tools such as fuel-estimation guides, navigation and tips. For example, a Sacramento-Grand Canyon jaunt would take nearly 13 hours and cost $143 in gas. Sync up directions via the free app (available for most smartphones), and hit the road. www.roadtrippers.com.
