Wow, I missed this post way back. I never get under a car without jack stands and some type of wheel chock. I also try to keep the jack underneath the car somewhere just in case the stands fail. When I was 15 years old and working at a bodyshop/tow-yard I witnessed one of the workers legs get crushed when a F350 Dually sling truck fell on his legs and pulverized them. The picture of his bone protruding through his skin is forever burned into my brain so I don't skimp on safety. Lifts make me terribly nervous. I've seen cars fall off of them. I feel better about the jack and stands.
