I am a fan of using Google to print my route. I get my maps to a detail level of every county road and still have a couple miles in any direction from my route, just in case anything unforeseen comes up, or I like a different road. I then print a few overview maps just to be safe. Before my trip I cut the edges of the paper off and make squares, fold them up, and put them in my handlebar bag. I get about 8-10 miles on one sheet of paper, then I just rotate. Also, the small size allows me to handle them easily while riding...
