Back in the early '70s while on vacation with my family, I saw a bike flag 'pole' that was also the riders' fishing pole. He had a multi-color spinning helix (you see similar wind chime/kinetic sculptures at garden centers) at the tip of his fishing pole, attached to the bike much like posts #14 and 17 above.
