As Memorial Day unofficially kicks off summer, more people will start bringing out the boats and heading to Lake Red Rock. Marion County Sheriff Jason Sandholdt reminds boaters that safety starts before you even leave your home. As you check your trailer and pack the cooler, Sandholdt says it’s also a good time to check for safety equipment like life jackets and fire extinguishers. Sandholdt adds that if you plan on drinking, you need to have a designated driver on the lake.
