David Sklar and I met more than 20 years ago, when his son Max and my son Greg were in kindergarden at Claire Lilienthal school in San Francisco. Over the years we have done many morning rides together, and David has done some long rides with Bill Poceta and me.

Among his skills, David is a mathematition. Here is the cover of a text book he recently wrote. While he rides, David often works on math problems. When he does it out loud, it can be unsettling.
