After the boys rode their bicycle past me, a car drove past, and carefully moved towards the center of the road to give room to the boys on the bicycle. The driver of the car presumably is considerate for bicyclists, as the car was carrying a bicycle as well.
I have never ridden a bicycle in Costa Rica, but I am very cautious when riding a bicycle near our home in Scottsdale, Arizona, as people driving cars at times do not notice bicyclists. At least on country roads in Costa Rica the bicyclists are more visible because there is less traffic.
We have photos of the Himalayan kingdom of Bhutan this week on our Viva la Voyage travel photo site.
