A great alternative in Utah by students.

Mellissa Evans thought she had found a new way to rein in her expenses as gasoline prices escalated.
The Tooele High School senior began hoofing it to school this week on her 11-year-old gelding, Nighthawk. Joined by junior Chapa Stevenson and her horse, Wink, the pair made the 30-mile trek between their homes in Rush Valley and school twice a day on horseback.
But school officials told them Thursday that horses on school grounds are against the rules.
"I guess we have to go back to carpooling," said Evans, who kept her horse in a stall inside the high school's animal laboratory while she was in class. "When you have a car that gets 10 miles per gallon, you have to do something."
In the weeks since gas prices reached record highs, people throughout Utah have taken creative steps to reduce their gas bills.
Some are taking big steps, such as trading in gas-guzzling vehicles or trying to find a job closer to home. Others are making smaller changes, telecommuting one or more days a week or trying to drive less on weekends.

so its a good idea to use horses to replace cars as transportation instead.
of coures u gonna have to feed them and make sure they have enough water for the long journey. and also u have to leave early since its slower in goin to school. but it saves money i believe.

Then you'll just speed up soil depletion?
