I'm going to do a road trip next week, starting in the DC area, heading west to Yellowstone, then out to Vancouver, WA, then down to Crater Lake, The Grand Canyon, after that it's tentative- thinking about Bryce Canyon, Rocky Mountain National Park, Diamond Crater State Park (Ark.) and up Skyline drive. I'm open to suggestions though- I expect I'll spend a couple of days at Yellowstone, but I'm not sure after that. Interesting landscapes and wildlife are my preferences. Other than at least 7-10 days in the PDX area, I'm not making deep plans. Thanks for any suggestions.
