Best part - my commute is better for me than any cup of coffee. I am wound up and ready to go when I get to work. While everyone else is groping for their morning stimulant, I just rode mine in.
Worst part - (1) executing a three lane sweep to make a left hand turn to get downtown. If I can time the traffic lights correctly, this isn't a problem. The bike lane ends about a quarter mile back, so I have to take the lane and hope some redneck in a pickup understands that I belong there too. (2) another left hand turn on the way home. I don't even bother attempting to get into the left turn lane, the traffic is just too much. I cross the intersection and punch the ped crossing button. I have found that to be much easier.
Four wheels move the body, two wheels move the soul.
