The City of Riverside will have their annual Trick-or-Treat night on Monday from 6-8 p.m. City Clerk Becky LaRoche encourages residents to turn on their porch lights to make sure trick-or-treaters know they can stop there for candy. There won’t be any other official Halloween party in the city, as they had their Haunted Trail event last weekend. LaRoche said the weather was perfect for the event, and they had approximately 70 attendees, which she said was a typical turn-out.
