The latest on Brother Dave is that he and a couple of business partners own a bicycle shop where they also sell and rent boats. During the summer of 2009 they started doing guided tours. Below are photos from their maiden voyage on the Oconee River. Halfway down this page there is a diagram of where this is in Georgia. Don't forget this job is in addition to Dave's regular job, whereas June 30th 2011, he will be retiring. Dave says "that the old canoe trips must have stuck with me, because in the past 20 years I must have probably paddled 1,000 miles of river in GA, NC, and FL. Maybe a Cromwell reunion on the river one day."
