GW4BOW, sounds like you have a great plan. I have 5 kids, and the older 4 like to hunt sheds with me. I started out with them on my shoulders hiking through the sage. I normally spot the antler and then wander towards it until the kid spots it. There is nothing funner than being there with your kids when they find their first sheds. I took my 3 year old boy out today and we found a matched set of 3 points. He was proud as a peacock that he found them.
My oldest daughter started out that way, and last week she and I went to Arizona to hunt elk sheds. She is almost 9 now and she has picked up quite a few deer sheds, but never an elk shed. We had split up in a sage flat and she started yelling that she had found a big one. It was a 7 point hard white off a bull that was around 340" It was neat to spend time with her, and to be there when she found her first elk shed.
It's not too tough to fill a suburban with kids if I say let's go shed huntin!
Good luck!
