I don't know about many of the guys who rode with GWB in Maine, but what I can tell you is that in this photo the man on the left of W is Brandon Gillard, who is the co-owner of the Kennebunkport Bike Shop. The couple on the right of W are Cyndi and Chris Smith, who are co-owners of CA Smith Photography in Kennebunk, Maine and they've been friends with the Bush family for years. Obviously, they all are very passionate bike riders. Hope that answers your question!
