I enjoy riding to work as well. Unfortunately I need a car for work some days so I can't bike everyday. With the sun not coming up until later I also have to skip the days that I start early.

The route that I take... to avoid higher crime and traffic areas and also so I can enjoy the scenic parkways and bike trails...is 14.5 miles each way.

I definitely see more bike commuters now that the gas prices are up. At my LBS they said they've had a number of people bringing in old bikes that haven't been ridden in years for a tune up so they can bike to work.
