Don...you & I live in one of the calmest weather areas on the East coast. We get an occasional unpleasant event, but it seems that a large % of serious rain and snow..etc, ends up going north of south of us.
   Years ago, we had that earthquake that shook the Washington Monument, but it happened way to the south.

If global catastrophes happen, all bets are off. Until then, I think I'll not bother with stockpiling stuff that won't help much anyway...
