hopefully more manufacturers begin to offer natural gas cars, so that gas stations will be more inclined to carry natural gas. only then would it be a worthwhile investment, because at this point, its geared towards the upper-middle class home-owner who can afford to install a pump at home. but that demographic tends to buy SUVs and Minivans anyways, don't they? So I'm sure saving money on gas isn't as high a concern as people with a lower household income...
