Okay, maybe not the most expensive, but certainly a lot more than the builder expected to spend.

The Detroit Free Press reports that a Michigan man, William Colston of Cheasing, built a professional quality sand volleyball court on federal land that had been designated as a preserve for an endangered bird.

The land had been set aside to protect the Kirkland Warbler in northern Michigan near Traverse City.

Colston was subsequently convicted of knowingly occupying federal property and was sentenced to one year probation and fined $35,000.
