The Pan-American Highway passes through Tulcán, over the Rumichaca bridge and on into the Bolívar province of Colombia. We had planned to visit the closest Colombian town to the border, Ipiales, but things were a little shaky the week of my visit so we decided it best to alter that part of the trip. David did want me to see the busy border crossing which is full of activity and money-changers on both sides of the border. (Ecuador uses the United States dollar, but Columbia uses the peso). So… I spent 3 minutes in Columbia, crossing the border, and then right back to Ecuador.
