We posted this topic recently on Facebook, but I also wanted to open up a wider discussion to any and all potential GPT hikers out there. Like the North Country Trail, The American Discovery Trail, and the Ice Age Trail, The GPT will incorporate a fair amount of road in order to connect with existing trails. The goal will always be more trail and less road, and there is plenty of time for that evolution to occur. However, the simple fact is that roads will need to be used.
Great care has been taken to select the most scenic and least used roads possible. They are generally dirt roads, and having traveled many of them personally, I find them about as enjoyable as a road can possibly be. Many of them in the plains region are extremely lightly traveled by vehicles, and at times, many hours passed between cars or trucks.
That said, what are some thoughts out there on road hiking? Have you taken a long road hike before? What are the disadvantages, and are there any advantages?
