OK, walking to replace driving completely is not realistic. But there are times when walking can replace driving. And as the price of gas continues to skyrocket, every car trip has become something that is carefully considered.
The thing to balance is time spent walking versus the health benefit and (admittedly minor) monetary savings. But even if one walking excursion a day to the local grocery store doesn't add up to much if one person did it, imagine if millions walked to the grocery store and bought two bags of groceries instead of driving. Now we're talking about saving a lot of gas.
So let's all pick a day, and walk to the grocery store! Anybody with me?
