Just trying to be responsive to those who are either participating or not participating in handing out treats. You may wish to consider printing off and hanging one of these signs on your door or garage door to identify to those going from house to house.
This was on another post and I thought it was a great idea.
Here are the actual links to the PDF which can be downloaded and printed.
My recommendation would be to not risk exposure especially now that we are in a CODE RED. If you intend to participate maintain the protocols and have a Safe Halloween.
