Bolivia, fall (our spring), 1968. Alejandro (l) and Porfirio (r) checking out some radishes from a little demonstration garden plot. The altitude, cold and dryness of the Altiplano are not conducive to many food crops. However, some cold-climate vegetables such as radishes, carrots, lettuce, and turnips can be grown, expecially in walled-in areas. They are a big help in improving the everyday nutrition of the residents, which usually consists of boiled potatoes, sun-dried boiled potatoes and naturally freeze-dried potatoes. The two guys were community-development employees of the Bolivian gov't in a short-lived but very effective program to help their neighbors live better. I spent lots of time with them, doing projects, talking up ideas, being frustrated, celebrating successes, traveling together many bicycle miles, through rain, hail and darkest night. They were some of the finest individuals I have ever known, and are among my best friends.
