The mammoths are on display at the L. A. County Museum of Natural History . A mile deep and 277 miles long, the canyon is a sight no one ever forgets. Our nation's capitol. When you're finished touring for the day, pack a snack and head to East Potomac Park, between the Potomac River and the Washington Canal, to burn off some energy and watch the sunset. On the tip of the park is the Awakening, a gigantic statue of a man emerging from the ground.
Kids can climb on it and into it, and it's a great photo op.
Be prepared for intense humidity. It gets very hot and humid in the city come summer, but everything is air-conditioned and there is so much to do. Kick off your shoes and spend some time on this white-sand beach bordering the Atlantic Ocean. The city's transit system makes San Diego accessible without a car, and it has seventy miles of beaches on the Pacific Ocean, plus all the museums, amusement parks, and other attractions. Try the Tower of London , Buckingham Palace, and the Changing of the Guard ceremony, or Hampton Court just upriver from the Tower.
