Garrett,
I'm currently a Cub Scout Den Leader. I created a little HAT&S PowerPoint slide set based upon what I could find on-line. I couldn't find a SAR team in my area that did the presentation.
If you'd like a copy, post an e-mail address.
What I did was buy little cheap fanny packs from Orientaltrading.com for each boy and then they filled them with:
>> Whistles on a stretchable wrist lanyard, also from OrientalTrading.com. For my own kids I replaced the cheap whistles with Wind Storm whistles.
>> Orange trash bags from Spectrumtrashbags.com, with a demo of how to tear a face hole. I would suggest the parents pre-slice a face opening.
>> Princeton Tech white LED lights added to the wrist lanyard, on a great sale from Campmor.com. They're not on sale anymore. This isn't mentioned by the Hug a Tree people, but I figured many kids are naturally afraid of the dark and this might help.
The boys (and my kids) are expected to have this kit with them on all outdoor activities.
