A good friend of mine was involved in a traffic wreck last week. He was traveling east on a two-lane state hiway in west Texas, when a gang truck, traveling west, failed to yield and turned south in front of hm. He swerved to the left and hit the heavy steel bed of the gang truck. He was driving an '08 GMC 3500 cab/chassis with welding bed. The engine of his truck wound up under his right arm, where his console used to be, and his right leg was under the brake pedal. He had to be cut out of his truck and airlifted to Midland for treatment of his injuries. He now has a rod and some screws in his right femur that suffered a compound fracture. He showed me something that has me baffled. His wallet was in the console and had about $5-600 in it. The bills that were in his wallet are as fragile as dried leaves. He had the cash in a plastic baggie and it was all crumbling to pieces! I saw a couple of bills that were at about 30%, the rest were at about 2-5%. What caused that? What deploys the air bag? Could that have caused those bills to do that?
