State Water Patrol officials say this weekend is the busiest one of the year for them, as thousands of Missourians try to take advantage of some time off out on the lakes. Sergeant Ralph Bledsoe says the numbers of boats on the waters will be very high in the evenings, as many people go out on the water to watch fireworks displays. He says boaters should check their lights before heading out on the lake. Bledsoe also warns shooting fireworks off a boat is illegal. And he says boaters must not drink and drive, adding the Water Patrol will be watching.
