Halloween falls on a Wednesday this year, so most trick-or-treating this year will be held on a weekday.
If you see an Arnold police car, be sure to visit. Officers will be giving away bags of potato chips on Halloween night.
Most young children will begin trick-or-treating just before sunset while older kids will likely stay out a little longer in the evening. Sunset for Halloween is expected at 6:02 p.m., according to The Weather Channel.
Be sure to dress the kids warmly for the evening. While no rain is expected, Fox 2 is forecasting a high Wednesday of 54 and a low of 35.
