Dagny...a ball chain necklace with a whistle and Photon (Fenix E01 etc), plus a bandana would be very good on body EDC for students in tornado country... never mind the back pack... a metallic "dog tag" with name, parent contact number and any medical conditions included with the neck chain....a "skate board" helmet covering the rear of the head would be a good inclusion to the back pack along with a pair of safety glasses for flying debris...real shoes not sandals...
