one of the "paper labs" I did with my students was a hurricane supply check list... it identified the threat, offered a solution, and provided space to write in an alternative solution...additionally it identified the location within their home where it was actually stored at....personally, I use a wall closet shelving to provide a central location for those supplies that "most" of the time would be considered emergency supplies...FAK, cook stoves, kero lamps, LED area lamps, potable stored water, Sawyer 5 gal filter kit...a rolling tool chest houses the dedicated electronic gizmos..
