I have always made sure I was home from work or more recently, hunting/fishing, in time to put on a mask etc. and answer the door as I recall how much fun I had as a kid. I always put out a bunch of decorations as well. But this year ? I think I may just post a sign saying "sorry, see you next year." All the young ones these days walk around with parent chaperones (I would have died before doing that!) and the older ones can read. As for a bowl of candy bars on the porch, what if one kid who is asymptomatic burrows to the bottom for a Nestles crunch and the next kid who has asthma catches it and dies ?
