It is amazing how the panicked lemmings react sometimes. If you stood in Starbucks with a friend and said out loud...
"I'm going to duct tape my windows and doors so the radioactive dust won't get inside and start wearing masks..."
There would be a run on duct tape and masks tomorrow and people would be tweeting that they were taping themselves inside. Stupidity is like a wildfire, it spreads quickly.
Just imagine how they would react if a real catastrophic emergency hit your area. All these people running around buying iodine, most likely don't even have a proper earthquake/survival/emergency kit, flashlights, etc.
Once the demon-bitch left my house and took her shit, I had a pretty empty closet downstairs. I converted it into a earthquake supplies kit. The Government says "3" days. I can go more than "3" months easy. (It's amazing what you can come up with when you're bored.)
