I was gonna suggest the SXR vid but someone else found it. The SJ vid is good as well. I agree with an above poster as well, proper maintenance is a very good topic. Lanyard safety as well, attaching to your life vest vs. wrist. Your in AZ and know no safety classes need to be taken in this state but it would be a great idea if Game and Fish did make it mandatory.
We were out at Pleasant a couple weeks ago and some morons on couches were turning donuts in the no wake zone WITHOUT life jackets. I ran over and told them to knock it off and sure enough both people on the skis were 13 or 14 who probably had minimal experience on the skis. I got dirty looks the rest of the day, but whatever.
I know most of us do it as well, but you could also discuss drinking while riding.
