Halloween falls on a Wednesday this year, so most trick-or-treating in 2012 will probably occur on a weekday. 

If you see a Maryland Heights Police car, be sure to visit. Officers will be giving away candy on Halloween night.

Maryland Heights has no official Halloween hours, so it will be up to parents to remind their little ghosts and goblins to venture back home at a reasonable hour. 

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. The channel's forecast is a high of 61 degrees and a low of 45 degrees, with no rain expected at this time.
