Someone needs to give the Dr a heads up that putting notes in other peoples mailboxes is a federal crime. Don’t do it. There are other ways to communicate. Tape a note to their front door or speak to them.
From the article:
“McDonnell also recommends checking in with neighbors and reminding them of the presence of your animals. She’s considered leaving notes in her own neighbors’ mailboxes and asking them to share when they plan to set off fireworks.”
I hope the Chronicle can edit that suggestion out of the article.
