We are driving to PV this year and would like to tour the Copper Canyon along the way. We will be coming from the east coast (NY) driving the southern route. (route 10). We are looking for advise as to the best place to cross the border and get to the Canyon. We will spend about 3 days touring the canyon and then onto PV. We are not sure whether to start in Los Mochos or Chihuahua. Thanks Judy
