I quit bike commuting a few years back it just stop being enjoyable. This after observing way too many close calls with careless drivers. I just ride for fun now. Also the winter riding became too hard on me, luckily I live in an area that has great mass transit so it is not a big deal. I must say now days as I walk around where I work it amazes me how more cyclist aren't run over considering every other car I see while Im walking around work seems to be driving lime a maniac.
