I'm really getting into US road trips, and was looking for some good ideas. This year, after my Germany trip, my 12 year old grandson and I took a road trip together. We left Duluth, headed west through North Dakota (stopping at Teddy Roosevelt NP), then to Livingston, MT (got there the night Yellowstone flooded), then down through Idaho to Salt Lake City where my brother lives. We stayed there a few days then all of us drove down to Moab, went hiking in Arches NP, and went rafting. From there we drove to Evergreen, CO, where my sister lives and spent a bit of time. Then homeward via Nebraska and South Dakota, visiting Mt. Rushmore, Crazy Horse and Badlands along the way.
I'm already planning a late summer/fall trip next year from Duluth to PEI. I'm thinking I will take the northern route through Canada (via the UP in Michigan), stop in Quebec City for a visit, then head onward to PEI. On the way back, I plan on heading down through Maine towards the Berkshires in Massachusetts (I have a cousin there), then over to Toronto, CA and back home. I know it will take at least 3-4 weeks, but that's fine.
But I'll be looking for more trips after that and would love to get some ideas here from others. Or any thoughts on the trip above to PEI. I visit my brother and SIL in Florida every year in January and I've been to NOLA many times so probably would not head southeast. But I am intrigued by the Pacific Northwest - I've been to Portland, OR before but that's about it. And of course, any other places.
