...suggested moving your crop, at least indoors. I would be very wary of a UPS driver that went to all that trouble to get into your backyard.

I have worked as a courier, and NONE of the guys I worked with would have gone to such lengths to enter someone's back yard. They would have left the parcel up front (out of sight if possible), or left one of those little notice thingies that says where to call to arrange another delivery, or to pick it up.

The fact that he basically committed 'breaking and entering', by the legal definition, suggests to me that he was using his job as a means to scout out or 'case' places, your house being one of 'em. Move /all/ your plants, if you can. Now. If nothing happens in 2mo, I might think about moving 'em back, but don't keep any on the deck if you can avoid it.

And, if you have the means, install some hidden cameras, preferably ones that work in darkness and that record their video to somewhere secret in the house, or perhaps offsite. You might be surprised at who shows up...
