News sources, blogs, email chains, and periodicals publish lists of "stupid laws", which are supposedly still on the books. One particularly amusing one:
Any motorist who sights a team of horses coming toward him must pull well off the road, cover his car with a blanket or canvas that blends with the countryside, and let the horses pass.
This is attributed, by sources like a local Philadelphia news TV station, to Pennsylvania state law, but no detailed citation is provided. Other websites, of even more dubious provenance, add the following:
If the horses appear skittish, the motorist must take his car apart, piece by piece, and hide it under the nearest bushes.
The only sources I can find are other lists of stupid laws. Does this one have any basis in fact?
