Last year, when I had bat-fever running through my veins, I met a man on the other side of the neighborhood. I had seen him one time, out in his garden, taking pictures, I used to think, of flowers. And when I saw him out there the day I met him, I assumed that he probably was an ecologist type of some sort and I shamelessly walked up to him and introduced myself. As I conversed with him, I learned that he was not a career ecologist, that he was retired, and that he studied, took care of, and took pictures of, his surrounding environment as a layman. Being interested in such things myself, I immediately got caught up in the facts and information he began to share with me.
