Writing was something I did, I still do, very comfortably. Putting down your thoughts, observations, on paper. First, I began to write by observing animals directly. That was the first step. Then taking a little overview, you move onto management of animals, and management of zoos, not based on individual species. The third step, where I am now, is to look at the history of zoos. After all, if you don’t know where you have been, you really don’t have a firm grip on where you are along how to look into tomorrow. So yesterday, today, tomorrow.
