At the focus is on the Bob Barrows Bearhawk airplane. However, as the 'unofficial' group we also discuss a wide variety of off-topic subjects ranging from airplanes and flying techniques to cars, firearms and everything in between. The group has attracted a uniquely experienced cadre of people from many disciplines who can supply answers (and opinions) on subjects from the intensely technical to the philosophical to the political. It's a fun group.
