OK, I'm game.
I wouldn't call her Charlie, I'd call her by her name. And I don't have a kid. But, really, why are they stuck and I'm not?

Easy answer: call the power company. they can kill power to that area (ideally you have the pole number, but if not, hopefully they can figure out the road). And, oh yeah, 911 will help too, since the fire engine's typically carry lineman's gloves. Don't think they'll just mosey over and pick up the line, though! AFAIK, you don't need a lineman to turn the power off, you need a lineman to repair the line.

If I can't get to them, power can't be turned off, then yes, I'm sorry, but you'll have to ride it out.

To the OP - that WAS good advice. Stay the heck away from power lines.

Edit: Actually, it'd be interesting to get DR's input on this. Or a professional lineman.
