Reply #12: Accidentally starting a forest fire while mowing your lawn gets 4 years in prison.

I figure it should be a few multiples more:

In August 2004, the Bear Fire burned 11,000 acres and destroyed 88 homes and other buildings in Jones Valley. William Matthew Rupp of Jones Valley was sentenced in 2006 to four years in prison for accidentally starting the blaze with a lawn mower after neighbors had advised him not to mow on a hot afternoon.
