A few months ago, I arrive at a resi way out on the end of a dirt road. I park at end of driveway, start walking up to house, three pit bulls show up and are obviously agitated, but they have the invisible fence from what I can see. I can see how far they dare to come, so I left the packages about 10 feet from them on a bench which is undercover. I had already blown the horn when I arrived, and no one came out. Later on, get a message from a CSA telling me they're p-ssed I didn't leave them at the front door, even though I had entered 'dangerous dogs' in the comments of the POD screen. So whenever I go there now, I blow the horn for a few seconds, give 'em two minutes to show they're home, if not, I tag the mailbox. They asked CSA for me to call them when I get there, I told her no, Fedex doesn't pay for my phone. Haven't heard a peep since the CSA informed them of that.
