Basil, I hear what you're saying, but those risks can't sometimes be avoided- this accident in Banff killed 7 people, all of whom had avalanche training and were traversing upslope in a valley across from the slide:
I saw a video with pics of this area and interviews with survivors. They had all the gear, looked at all the info, and made an educated decision... and a random event happened.
Especially with kids, I think you need to be over-cautious. If you 'learn em the cowboy way' now, and they're the ones that will be setting off slides above you on Berthoud in 5 years. You might be able to enlist a Level I instructor from NSP or one of the schools around the state to donate a day of 'education' (not a full Lvl I) in order to get these kids some info. Then MAYBE find a "safer" area, with trees, to take these kids into.
Hell, the liability issues alone are scary.
