When waves are crashing against the pier, it's not safe to venture out on it. Lives have been lost by people who were hit by a wave and knocked into the water. Waves are high today and kite surfers have been make the most of the wind.
Whenever I hear sirens, I hope that someone has not gotten into trouble on the big lake. The red flag is flying. That means it's not safe to go in the water, however there are always some that do.
