To add to this, some organizations like the American Cycling Association go to great lengths to publish quality bike tours (or “shared rides”) as guidebooks, available either to members or for a fee. Some of these tours are in a slow process of evolving into more formal designated routes, just as the TransAmerica Trail became U.S. Bicycle Route 1 76 in the 1970s, with the tour serving as a “corridor” for officials to consider. This causes us some difficulty, because we have mapped some tours but tagged them as essentially the same thing as designated routes. Now we find a need to somehow distinguish between the two.
