A couple of unique trick or treating events are being held on Tuesday in Pella. Pella Regional Health Center is hosting a Halloween open house in the Long Term Care Activity Room. The residents will be passing out candy from 6 to 7:30pm. There is also a Trunk or Treat at Trinity Reformed Church. Trunk or Treats are where many cars park in a parking lot, and decorate their trunks. The kids can go from car to car picking up their candy rather than from house to house. The trunk or treat is from 6 to 8pm.
