I am doing a demo for VBS at my church (1st grade through 5th) on camping gear/survival. I was thinking about displaying 2-3 person tent, a bivy sack, water filter, couple different single burner pack stoves, 1st aide kits, rain gear, fire starters, whistles, mirrors for signaling etc. I have my dept chopper with a rescue hoist coming one night to show a rescue operation and our man trackers coming to show them tracking lost persons. Does this sound like over kill or not enough? I really want them to have fun, any thoughts would be greatly appreciated.
