 Good evening, I'm Sean Anderson. I'm Anne Kramer. Our top local story this hour, world leaders are set to meet tomorrow and through much of the week here in D.C. for the NATO summit. Now, 75 years ago, the North Atlantic Treaty was signed by 12 countries meeting right here in Washington. The summit means a lot of road closures, extra security this week. WTOP's Neil Augenstein says the NATO gathering will also make it harder to run or visit some businesses.
