We almost always use Travelocity to search for rental cars, and usually end up making the reservation through them also. Very intuitive and easy-to-use. You search results are always ordered by default by lowest cost for each of the car size categories, making it easy to select what you want.

- Lyndon Johnson, on signing the Wilderness Act into law (1964)
