An idea whose time has come back?

horse.JPGI read recently about some farmers who had ditched their tractors for mules due to the soaring price of gasoline. With economists predicting no end in sight for rising prices, we may be seeing more horses and mules on and off the farm. And this morning I heard about some kids who actually rode horses to school. The principal did not object and even provided food for the horses. Can you see it now, special lanes for this original mode of transportation? Can horse “dealerships” be far behind? This could save some gas but what about the special emissions :-)?
