"A horse is a horse, of course, of course,
but the Vehicle Code does not divorce
its application from, perforce,
a steed as my colleagues said.
"'It's not vague,' I'll say until I'm hoarse,
and whether a car, a truck or horse
this law applies with equal force,
and I'd reverse instead."
The facts of the case are equally entertaining:
Riders Keith Travis, 41, and Richard Noel, 49, were charged with drunken driving along with a man driving a pickup who allegedly rear-ended the horse Travis was riding away from a bar on a dark country road.
