We've reached the mid-point in the dog days of August, so it's not too soon to reflect on some cool outdoor holiday decorations to acknowledge the signposts ahead on the calendar, beginning with Labor Day (U.S.). Falling on the first Monday in September, Labor Day is one of those "in-between" holidays. Depending on your inclination, Labor Day can mark either the end of summer or the beginning of fall (Is your glass half empty or half full?). Accordingly, these top picks for outdoor holiday decorations are split 50-50 between summer themes and autumn themes. There are ideas for you here whether you wish to celebrate summer's last hurrah or plan early for the ghoulish delights of Halloween.
