Angelic trunk or treat

Can't believe October is already coming to a close, I'm scrambling to get my costume and decor ready for this year's Trunk or Treat where we decorate our cars and hand out candy from the trunks in the church parking lot.  Last year we got a downpour that drove everyone inside, I'm hoping it will be drier this time around.  We usually get about 180 kids.

I'm using my silver dance wings and doing up an angel costume, complete with white wig and fluffy halo on a headband.  Sparkly blanket in the back of the car with twinkle lights and such should work, figure that way if it rains on us again its something relatively easy to transfer to a table inside and still have a theme. I did this once before a while back, the preschoolers eyes about pop out of their head when I slowly open the wings.  :-D
