Thanks for your input everyone.
Draclvr, I would think you would be among the first to see it, being out in the country. By my house, I can see packages stuck in trees and on roofs, hitting people on the head, or landing in dog poop that nobody cleaned up.
Ana, I don't care for the Amazon drivers. I really prefer FedEx, UPS, or USPS, although FedEx threw an (unexpected) envelope on my porch one day without ringing the bell. Fortunately, my brother found it as it was a rather important piece of mail. I'd rather wait a day or two for my deliveries.
I read that Walmart is looking into this also, as they are trying to compete with Amazon.
