I ride mostly for commuting to work but do ride just for the fun of it also. Commute is 5.5 miles each way and I have bike lanes or designated bike routes the whole way. I try my best to obey the traffic laws and to ride predictably. I use lights and have some ANSI lime green shirts I wear when riding to work, my neighbors have commented on being able to see all the way down the street so they work. I started riding for fitness but now I ride every chance I get.
