On Oct. 27, Rock Row will host “Trick or Truck” from noon to 3 p.m.

The free event will mix trick or treating with on-site monster trucks, including Aftershock, the Guinness World Record-holding Big Red Monster Fire Truck, and Shaw Brothers construction trucks. There will be opportunities to climb into the trucks.
