Shirley, that is a great idea. Get on it.


In my opinion, I just simply follow a process:

1. Ask them if they want to hear why they should not dive beyond their training into caves in a nice and educational instructor tone.
2. If they refuse education because they know it all, I simply ask them to write down their next of kin phone numbers and place them in their vehicles. That way the sheriff officer that handles their recovery process will know who to contact.

If they are going to kill themselves, they should at least make it easy to contact their families.

Other then that and you are crossing the line and can get into legal trouble.
