Iím panning on taking a road trip for two months (66 days) from Yellowstone to North Cascades all the way down to Joshua tree then to Colorado. I plan to stop at 20 national parks and I will be camping most the time in a tent and sleeping bag. What are the best national parks? At those national parks what are the best campgrounds and trails/attractions. I will be getting a national park pass. What would be a good budget to look at if I was planning on driving 8000 miles? Not sure how many people will be with me but I know there will be two including myself. Has any one ever taking their dog on a road trip and made it work?
