A senior living community in Pella is opening its weekly social gathering to elder members of the public this week to provide guests with an inside look at the facility.  Vriendschap Village Marketing Director Kathi Gross says a free community meal, exclusively for local senior citizens, will allow guests the opportunity to interact with the residents and staff of the independent living community.  The event will begin at 5:30 p.m. tonight at Vriendschap Village, which is located in the Westport business area in Pella.
