In Argentina, we rented bikes from the friendly folks at Cordillera, and went for a casual scenic ride around the Circuito Chico, before branching off onto dusty back dirt roads.
Most of the route was great, but the last 6 miles into town were unpleasant riding: on the major and only road, plagued with thick, choking auto exhaust, no shoulders, and cars and buses regularly swerving and at times forcing us off the road.
