How Agrestic (and surrounding areas) went down in flames.

At the end of season 3, the menacing biker-suppliers tried unsuccessfully to push their shoddy ''ditch weed'' product on Nancy. So, going in for the tough sell, they beat up older son Silas as incentive. To protect the nest, Nancy formed an alliance — no doubt, a Faustian one! — with Guillermo and his Tres Seis amigos, who simply cut to the chase and burned the bikers' field of grass. Just one catch: The out-of-control fire spread through the Agrestic/Majestic area.
