But what about the maintenance costs and needs for a horse? I won't pretend I know anything about one but my grandpa raised pigs/hogs and well.... they were quite the headache in both upkeep and routine.
*pig-powered transport? ...NAH!*
I think I saw someone on the news last week using a cow-drawn wagon to cross the country or to reach the capitol (WDC). I don't think it was fuel related but more of the "we can do it" sort of thing.
But if you've already got the means for animal support, I don't see why not unless there is some silly law that says you can't (wouldn't surprise me if there was one somewhere in the codes).
