What this means for you

Loudoun County Public Schools are closed Thursday and Friday, Oct. 29-30, so the library parties, Mall-O-Ween and the Leesburg events fill those days. The Fall Fest runs 11 a.m. to 2 p.m. Saturday, before trick-or-treating starts at dusk. For Halloween night itself, read trick-or-treat hours in Ashburn; for the rest of the month, things to do this month.
