I was out in the backyard with Finn (my dog) when I heard a steam whistle...
I thought I was imagining it at first, but it isn't Christmas so Polar Express wasn't due.
It was a steam train taking passengers on joy-rides down a normal suburban line.
What was cool was seeing an old time steam train from the porch of my 1914 Edwardian house.
