 Hundreds of thousands of us expected to be along the National Mall on Thursday for the annual 4th of July fireworks display. WTOP's Scott Gelman says that law enforcement agencies are preparing for all types of weather and emphasizing safety for everybody in attendance. They're urging everyone to drink a lot of water and cool off in Smithsonian museums during the day. If major storms roll in, officers will try to clear the area first and then show people where to go until the weather improves. There is quite a large plan in place for that.
