Where are the mandatory rules posted for using jack stands, etc.?

[Terry]

I suggest we promulgate some other common sense rules.
1. When you see that someone has parked his car, trailer and tow vehicle at an event, don't park your own stuff to block him in or out. Why this isn't obvious is beyond me.
2. Don't borrow tools without permission and return them in the same or better condition as received.
3. Avoid making stupid anti-lawyer jokes.
