Not enough. We need our TEA Party people to express order “Don’t Touch My Junk” t-shirts and visit their local airport- shop, eat, visit the news stand, etc. for a bit of civil disobedience that is perfectly legal. If the t-shirts take to long to arrive, plenty of cities have places that can make them.
Make Nov 24 the “drive through the airport real slow” day, even if you have no other reason to go to the a/p.
