Mark sez, "Under TSA rules, various transportation workers need to pass background checks to receive biometric 'Transportation Worker Identification Credentials (TWIC)' IDs; this measure is allegedly necessary to thwart terrorism. This standard is being applied to employees of Hugh Moore Historical Park who operate mule-drawn canal boats at breakneck speeds of up to two miles per hour while wearing period costumes."
"We have one boat. It's pulled by two mules. On a good day they might go 2 miles per hour," said Sarah B. Hays, the park's director of operations.
The park's two-mile canal does not pass any military bases, nuclear power plants or other sensitive facilities. And, park officials say, the mules could be considered weapons of mass destruction only if they were aimed at something resembling food.
