An Enumclaw-area man who authorities say helped run a farm where people had sex with animals — and where a Seattle man died doing so with a horse — was charged with a misdemeanor yesterday.
Police began investigating James Tait, 54, and another man who lived at the rural Southeast King County farm after the Seattle man died of injuries suffered during intercourse with a horse in the summer, Enumclaw police said.

Hopefully nobody reading this story has a good enough imagination to have a mental picture of this incident. I'd apologize for the image if you do, but hey, I'm just the Spinguy.
