With the price of gas constantly fluctuating, walking has become a more popular activity. Even if you have to drive to the store, you don’t need to drive around the parking lot until you find the closest spot, or idle for ten minutes waiting for someone to leave the spot you want. Park in the first spot you come to and walk to the store. Not only will you save money on gas, but you will get some exercise. And, if you live less than a mile from your destination, walk.
