From the AP Wire:

Hobe Sound, Florida
Motorcyclist Christopher Jude Doyle, 44, died after striking a cow that had wandered onto Interstate 95 through a hole cut in a fence. The cow also died. Florida fences on grazing land have been cut in recent years by people trying to reach psychedelic mushrooms that grow around cow manure.
(Washington Post summaries 050603)

It speaks for itself.

I saw this on the back of a WMATA truck involved in construction at the Tenleytown Metro:
