Threat of Icy Roads
There was a threat of icy roads Saturday evening, and that kept attendance low this session (in fact, the club meeting that evening did not occur due to the weather). So a small group of students and instructors had a quite but productive day.
A Small Class at Fletcher House
Jay Drew, mirror class leader for five years, retired from that position and handed the leadership (and the clipboard) over to Ray Morits, who I am sure will do as good a job as Jay did. Here are a few photos from the small class held this day.
