RE: [at-l] Emergency Blanket

["L. Clayton Parker" <lparker@cacaphony.net>]

"Metallic" emergency blankets are made from Mylar, not pure metal. It is a
plastic that contains sufficient metal to make it reflective to heat and
incidentally, radar. I don't believe it is any more of a lightning
attractant than  for instance, a tall tree but it would definitely build a
charge under the right conditions. So if you are looking for quick
protection from a storm, use your poncho, not the Space Blanket.

BTW, a space blanket saved a hike once by padding my back from a broken pack
frame. For their weight, they come in useful in a lot of ways...
