 Good morning to you. I'm Dean Blain. We thank you for taking us along for your 1 a.m. hour Tuesday morning ride. We begin the ride this morning with world leaders set to meet later today, this Tuesday, and through much of this week, in fact, in D.C. for the NATO Summit. Seventy-five years ago, the North Atlantic Treaty was signed by 12 countries meeting right here in Washington. The summit means a lot of road closures and extra security, as you might imagine. WTOP's Neil Augenstein says the NATO gathering will also make it harder to run or visit some businesses.
