Seth Godin has a number of “random travel thoughts,” several of which relate to airport security:

• When I go through security, why do I need to remove a cardigan sweater but the woman standing next to me can keep her cashmere blouse on? Are certain kinds of wool inherently risky?

• What would happen if Imagineers from Disney designed the security line? Why not let them try?

• After inspecting more than twenty million pairs of shoes, have the screeners found even one dangerous pair?

• After seven years, why is random yelling still the way that TSA screeners communicate their superstitious rules to people in line? Will this still be true in twenty years?

Good questions all.
