Carl, I did no editing, but wonder if the angle and tree height may cover it. I vaguely remember someone mentioning a smoke stack but not what they said about it.
Heck, they may have said they recently took it down. I checked some of my other pics, but don't see any that would show it. There were just so many beautiful gardens just in Vancouver and with the excellent public transportation and just a bit of walking you can see a couple a day.
