Yeah I dont know why I didnt start commuting in the summer. I was just riding my bicycle around during the summer(I have a fixed gear bicycle for just messing around). I guess since it was winter, my friends didnt want to just ride around anymore. And I was having bicycling withdrawal, so I decided to get a geared bike and start commuting.
And yeah. The right gear makes a difference. I thought that I would be freezing my butt off. But actually, with the right layers (and lots and lots of tips in these forums), I actually am sometimes too hot and have to zip open my jacket a little. haha.
Oh yeah. I decided to add a light mounted to my helmet. Biiig difference to just having a light on your handlebars. Being able to look around is wonderfully nice.
