Cars can be big no-no's

Just use your bike. You can easily make your way in to town and run your errands on a bike instead of wasting gas driving and looking for a parking spot.

Riding a bike helps to not pollute, save you money, and make you physically fit.

What is nice is that all you need to buy is a bike (good bikes can be found for $200 or less), a $10 lock, and a $25 helmet. NO INSURANCE. Then, when you need to travel far see if you can use public transportation. If worse comes to worse you can see if there is more thing to do where you are traveling allowing you to carpool with zipcar.

But, if none of the above will work for you and you have to take a car I simply recommend to park in the shade. This will make your gas evaporate at a lower rate and use less electricity because you won't have to turn on the air conditioner to cool the car.
