Ridgefield officials have approved another controlled deer hunt between October 15th and January 31st.  There are 15 properties detailed by the Deer Management Implementation Committee to be hunted by those who have registered.  $1,700 was also approved for signage alerting residents that hunting will take place on the open space land between dawn and dusk during the week, except when school is not in session.  Controlled hunts have been held in Ridgefield on town-owned land since 2006 as a way to cull the herd, which was damaging forest understory, causing car accidents and carrying ticks that could spread Lyme Disease.  After this year's hunt, a public hearing and town meeting will be held about whether future controlled hunts will be scheduled.  The hearing will be on March 31st.
