YAPHANK - Suffolk County officials are urging residents to keep safety front-and-center ahead of Fourth of July. In a stern "do as I say and not as I do" gesture, Suffolk police packed a car with fireworks today and blew it up to illustrate the dangers associated with holiday pyrotechnic displays. Police say residents should play it safe and head to legal firework shows, rather than trying to do their own. County Executive Steve Bellone (D-Suffolk) says police are beefing up patrols to crack down on illegal fireworks this holiday. Officers will also be out on the roads looking for drunken drivers, and the county's marine bureau will be patrolling the waterways for drunken boaters, Bellone says.Where to see Fourth of July fireworks on LI
