Despite the forecast of more rain and colder temperatures tomorrow evening, the Optimist Club Halloween Walk for downtown Summerville has been changed again.  Yesterday, the decision was made to move the Summerville Halloween Walk to the Chattooga County Agricultural Building.  Today, the decision was reversed, and the Optimist Club says that the event will be held “rain or shine” in downtown Summerville.  No reason for the reversal in the decision was given.
