Due to construction activity behind New Fairfield High School, effective immediately, there will be no sledding or other recreational activity allowed in that area. The work itself and the location of construction equipment pose a safety hazard to those in the area. New Fairfield officials expect the work to be completed within the next 3 weeks.  New Fairfield Volunteer Fire Department is offering some reminders about ice safety.  They caution that the strength of ice cannot be determined just by its appearance, age, thickness, or the temperature.  New ice is usually stronger than old ice. Four inches of clear, newly-formed ice may support one person, while a foot or more of old, partially-thawed ice may not.  Ice also seldom freezes uniformly. It may be a foot thick in one location and only an inch or two just a few feet away.
