S.C. Johnson makes Ziploc bags. Buy now. Why? Homeland Security has relaxed restrictions on carrying liquids on airplanes. But only 3 ounces. And only if they are in a clear 1 quart plastic bag. Guess what? That's not a standard sandwich size. So, will there be a run on 1 quart plastic bags? Who knows. Bet the airport concession folks are happy too. Water and other former banned items can now be carried on, but only if you purchase them after passing through security. You got to love this country.
