Finally. Only two weeks late, Amtrak have delivered our package.
In the end I had to get the "delivery guy" to phone me on my mobile so that I could come outside and find him. So much for the notion that he might know where he was supposed to deliver things to.
In addition, it appears that a large mammoth has played football with the package in question. Yay.
We shall find out later if it's going back or not..
