I spent the summer of 1987 in Central America. Mainly I was in Costa Rica conducting research for my Masters degree.
But the folks at CATIE gave me a contract to develop a slideshow on sustainable natural resources. For some reason, I invented an excuse to travel to Guatemala. Perhaps I was working but I only remember going to Lake Atitlán and staying in Panajachel. On one day I took a boat to Santiago de Atitlán and on another I rented a bike and pedalled south along the coast.
