Public speaking isn't for everybody, and coming up with funny one-liners to impress your audience is sometimes a gamble. When El Paso County Commission Chairwoman Sallie Clark (right) spoke to about 200 people Wednesday at a Greater Colorado Springs Economic Development Corp. luncheon, she closed out her remarks talking about the need for business leaders, politicians and others to promote the community. She then rolled the dice: "Change is inevitable," Clark said, "except from a vending machine." There were no loud groans, only a couple of polite bits of laughter. The message for Clark: Don't quit your day job.
