Hi, we are planning a summer road trip for early June. We live in Cleveland, Ohio and plan on going to Mount Rushmore, Yellowstone National Park, Redwood National Park, through San Francisco, down to Los Angeles and around there and then to Death Valley National Park and onto the Grand Canyon, and eventually back home to Cleveland. These are just some of the major areas we want to visit. We are thinking the trip will take about 2 weeks. I would appreciate and comments or suggestions in regards to saving time or visiting other great spots. My son loves amusement parks.
