Walking

Now the cheapest way to get about still is and always has been plain old walking. You can't beat walking when it comes to saving gas anyway you look at it. If you live within a couple miles of anyplace you need to go try walking, not only will you not spend any money on gas, but walking is one of the best forms of exercise there is, you'll look better, feel better, and think of all the money you'll save just by not cranking up the car. Need to pick up something? get a back pack or a small push cart, even a kids wagon will get the job done, after all you won't be walking that far and all you need is something to carry stuff with. I find that wearing comfortable shoes and lose fitting clothes makes the walk all the more enjoyable and it helps if what you have on is bright or noticeable so as to attract the attention of others going by in cars (if you happen to be going in a place where there's no side walks).
