I was lucky enough to teach and to live in Costa Rica for four years, many years ago.
There was so much I loved and admired about this country: the complete lack of military spending; the emphasis on education and the great respect Costa Ricans had for teachers; their unashamed search for peace and most of all, their protection and love of wildlife. When we lived in Costa Rica it had the highest percentage of its land mass given over to nature reserves of any country on the planet and the diversity of habitats in this tiny beautiful country is breathtaking.
San Jose, the capital, is not the most scenic city in the world, it has pollution and ugly malls, but my attention was caught by this article on one of its satellite towns : Curridabat.
