Going Green?

With gas prices soaring I have been considering "going green". It has become very tempting to start riding my horses to run all my errands in town. I think the local police would love it!! I have also thought of starting my own lawn mowing and fertilizing business. My only fall back is that I have no where in town to keep my horses. I still need to research any laws restricting me to turn to this alternative means of transportation. I think this is one way of "going green" that I can actually afford.
