A 35-foot artificial Christmas tree was installed at Memorial Park in Slippery Rock, Nov. 9, with the help of students and faculty from Slippery Rock University's Hospitality, Event Management and Tourism Department, as well as Slippery Rock Development Inc., the Slippery Rock Volunteer Fire Company and the Slippery Rock Municipal Authority. The tree will be a focal attraction of the Slippery Rock Festival of Trees, a 10-day event over three weekends in December that will include food and craft vendors as well as horse carriage rides, organized by students in SRU's Event Productions class.
