New Fairfield firefighters are offering some ice safety tips including to never go out alone, and have a friend able to rescue you or go for help if you fall through the ice.  Pets should be kept on a leash.  If a pet falls through the ice, New Fairfield Volunteer Fire department urged people not to attempt to rescue the pet, but instead go for help.  New ice is usually stronger than old ice.  As ice ages, the bond between the crystals decays, making it weaker, even if melting has not occurred.  Beware of ice covered with snow.  Snow can insulate ice and keep it strong, but can also insulate it to keep it from freezing. Snow can also hide cracks, weak and open ice.
