Pasto is Tierra Fría. In fact, it is COLDER than Bogotá. Like in Bogotá, people conducting business in this area (like your appointments at ICBF and the courts) wear business suits -- ties for men and panty hose for women. You’ll want to bring your sweaters and jackets, and warm pajamas as there is no indoor heat.
The people of Pasto are friendly, but shy. Many will bend over backward to be helpful and treat tourists well. They are helpful, but a bit formal. You’ll want to greet people with a handshake and a formal “Buenos Días, Buenas Tardes, or Buenas Noches.”
Just to show you an example of their friendliness, in preparation for writing this week’s blog I asked for help from a complete stranger – a person that my niece knows from Pasto. He proudly talked to me for over an hour about his city and department. Then, he offered, “Hey, I talked to my Mom in Pasto about your project. She told me to tell anyone who is going to Pasto that she would love to help them in anyway and can help them learn about Pasto’s culture and she will invite them to dinner.”
