Sudbury police are issuing a reminder for people heading into the woods this time of year.     Be prepared in case your vehicle breaks down and it takes time to find you.    That’s what happened over the weekend when two men and a woman on a four-wheeler were found several hours after their vehicle broke down.    Police say in this case, the group was prepared for the cold.   Police say wear the right clothing and footwear for outdoor activity.   Make sure your cell phone is fully charged and bring along some food and water in case you get lost and it’s a while before you’re found.
