Dr. Crislip’s posts are archived here. To the great loss of skepticism, but to the great gain of golf courses everywhere, in June, 2017 Dr. Crislip decided to abandon us to the wolves focus on other things. His wit and wisdom will be missed.

The opinions in his posts are, of course, his and his alone. The posts are written in what little spare time he has, late at night or in the early hours of the morning while his family sleeps.
