I have had kids from a boys home in Spokane out to see the 767 at GEG. It's always fun to see the kids sit in the left seat thinking it's pretty cool while I often wish I was somewhere else while sitting in the same seat. Kinda brings you back to reality.
Another thing I do is Young Eagles flights. It's quite the experience to introduce youth to light aircraft and take them for their first airplane ride. I once got a note from some kid I long ago forgot who became a CFI down the road. That also makes you think twice.
