I can't find the actual measurements for the apple near Cobourg, ON, but according to Roadside America, it has an "observation deck on top, and a restaurant inside". That's bigger than 7 feet high. The photo of the Cobourg apple, above, comes from nonamedufus.

When I hit the track this morning, it was basically 100% humidity. It wasn't actually raining, but there was a thick fog, and dew was forming on things as I watched. The fog lifted a little during my ten 800 m intervals, but it was still humid enough for me.
