For one full day this week, don't use (or ride in) a car. That's right ... leave the car at home and either walk, ride a bicycle or take public transportation (or even ... stay home). One full day ... 24 hours ... no car.
OR ... if you are already car free, write a post about not using a car. Include such topics as how to make it work, drawbacks and solutions, and why it's better for the environment.
I will be writing about my adventure (or non-adventure, as it were) with this concept tomorrow or Friday.
Can you do it? Do you already do it?
