"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."
- Justice Michael Eakin
