The Register will have the route maps showing which towns have bike shops set up in them and how long they will be there. It also shows where the main campground will be and where the register trucks will be. If you don’t get the map, just follow the black and orange arrows.
Towns often will be out the night before going through the campground handing out papers with maps, food locations and shuttle routs between the campgrounds.
During the day don’t worry about finding food. Stands will be everywhere. Often in pass through towns cheerleaders, scouts, and others will be in the streets trying to direct people to their places.sometimes a block or so off the route. Really no way to map out all the pass through towns and placard in-between. But the vendors often know where they will be the next day and will have a sign up. They also put plenty of signs along the road.
