I live in a concrete jungle. There are cement roads, homes, schools, stores, churches, factories, etc. Real estate is very valuable in Cartagena so every milimeter is utilized for residential and comercial space. My middle class residential neighborhood is about 75 cents from my personal paradise. Depending on traffic, in about 30 - 40 minutes on a bus, I can watch the sunset over the Caribbean, play tennis, go boating, and eat in 500 year old plazas from colonial Spain. I feel very lucky that I don't need to fly here or pay for an expensive hotel to enjoy such a beautiful place. There are many tourists from Bogota, Medellin, and Europe that have to do just that. School starts Monday so I will only be able to go down to Boca Grande and the Historic Center on the weekends or when you come and visit. Until then, my new paradise will have to be a 75 cent Coke at lunch time at my cement school.
