Sally rides 20 miles each day, to and from work. O_O. Six miles shuold only take 30 minutes.

The great thing about 'pleasure' cycling is that you take a nice, leisurely ride. You can sit down on any field or pub bench you happy past and you get to see lots of lovely countryside - without feeling bad for polluting it.

If you're getting rid of the car, cycling would be a pretty good option.
