COGS did some drafting and group riding practice on Sunday.  The ride is based on an old Seattle Bike Discord ride on the quiet Sunday roads around the airport.  After a discussion on technique and safety we rolled three laps around while increasing speed and decreasing distance between riders.   Everyone learned a bit and got more comfortable with the nuance of tighter group riding.   Thanks to Joel W. for adding some expertise to the ride.   We will do it again.     (photo credit: Dave Walker Cartoons)
