Instead, the agency chose Flame Safe X-T, a material that is supposed to protect wood from fire as well as from the weather, C.T.A. officials said.
Proper drying reduces the magnitude of dimensional changes due to shrinkage and swelling, protects wood from microorganisms, reduces weight and transportation costs, better prepares wood for most finishing and preservation methods, and increases its strength.
Cialdini has run successful experiments using social norming to reduce littering, increase recycling and protect wood from theft at the Petrified Forest National Park (telling people "please don't remove the wood" and showing a lone thief inside a red circle and slash worked five times better than telling people that many past visitors have removed wood, with a picture of three thieves).
