BBC NEWS | Americas | Bulldozer rage man kills himself>A shopkeeper, who went on the rampage in a bulldozer in the US state of Colorado to protest against local town planning policy, has killed himself.

Not the first time this has happened. A bizarre trend in the making:

Residents of Alma, in Park County southwest of Denver, are still rattled over what caused town native Thomas Leask to go on a deadly bulldozer rampage in February 1998.

The first one was over town planning, the second one was operating on instructions from God.

Both were crazier than bedbugs. Avoid all bulldozers if traveling in Colorado this summer.
