The mail box "at" my house is about one mile from the front door and up on the ridge. The post office annex is about 3 miles away.
I sometimes walk up to the mail box (although I am one of the few people who will - or can - walk straight up the slope of the ridge. It's a great form of exercise, but most people walk it in about 10-12 switchbacks.).
Most of the time regular mail does not work for me. So, I mostly use FedEx or UPS. Our regular UPS driver (Allison .... hi, Allison!!) is a complete darling. She generally pops in to pet the kitties and say hi to the doggies.
I don't think I've even met the regular postal delivery person. But then, it's never happened that I was at the box when something was being delivered.
