Motorcycles contains my personal motorcycling history, describing many of the machines I have owned since my first bike in 1967.
Atheism contains some of my writings on various religious topics, from the position of a philosophical materialist and freethinker. Freethought is a philosophy that is dedicated to the proposition that the human intellect should be unconstrained by religion or any other non-rational systems.
Afro links you to my essays relating to African-American issues, not to say that any person wouldn't find something of interest here.
3-D deals with stereoscopic photography, another hobby of mine. Only one section here so far, though: 3-D photos from the 1936 Olympics.
General contains essays on a variety of subjects not directly addressed elsewhere, such as dead friends.
