Ronnie - You might try to contact Shirley and Dave Hammond, SE at
shirham(--nospam--at)concentric.net who both have long been active in Urban Search and
Rescue in the Bay Area. I believe there's a special practice site over in
the west bay for cutting/shoring/and practicing extrications. Dave can put
you onto it.
