An interesting element for state-level bike and tourism planning: a state-wide network of bicycle routes and trails
Signs for the Route Verte abut a bicycle sharing station in Montreal.
While there are a number of instances of extremely long multiuse walking and biking trails, some as long as 300+ miles, I have written before about the Province of Quebec's Route Verte, a network of bicycle paths across the entire province, through and linking cities, towns, suburbs, and rural areas, totalling more than 4,500 km/2,795 miles of marked routes.
Now it is marketed as a significant element of Quebec's tourism program, with a special program to support provision of accommodations to bicyclists along the route.
Andy Clarke mentioned the Route Verte (and indirectly the Trail Towns bicycle tourism promotion effort in Pennsylvania) and it occurred to me that Maryland should work to develop such a program.
Pennsylvania has a set of state bicycle tour routes and Virginia is the only place I've seen that marks the national bicycle routes identified by the Adventure Cycling Association, but the Route Verte system and marketing program is much more comprehensive.
