Butterfly, where are you? I do travel sometimes for other reasons and perhaps it might be possible. I wish I had the resources to be able to just visit any show that wanted to try something different and give them whatever I could.
The fact that you are taking this seriously and looking for ways to provide meaningful and useful information to the crew folks is admirable. In all the years I spent on traveling shows and at theme parks, safety training ranked very high on dreaded events -- not because it was unnecessary, but because the classes or meetings were often so dull and uninteresting that it took a lot of effort to pay attention and then try to relate the information to my actual field work.
I had the misfortune to have to sit through an eight hour seminar on bolts and fasteners given by a high ranking member of the American Fastener Institute and this guy spent at least six hours on the physics of bolted joints. I really don't care that a bolt works by being elongated and the reactive force of that elongation is why a bolted joint holds, I needed to know how to be sure I had selected the proper bolt for the job (believe me bolted joints are a nightmare to deal with due to material grading, reuse, type of load appled, and a host of other factors). People working in the field don;t kneed a lot of detail, just the basics to know what they are doing is correct.
