The cut that connects Lake Union with Portage Bay and then to the lock as at Ballard has a trail alongside it.  We were taking a walk along there recently prior to getting some lunch close by.  We passed what initially looked like a normal hedge until we realized it had been shaped.  It was a pair of dinosaurs – a parent and a baby.  It was actually quite hard to find a good position to get a view of them.  The greenery tended to disguise the shape when closer in and the positioning of the two of them obscured the heads to some extent.  I suspect the best angle would be from above.  A drone would have been very handy.  It was a cure thing to come across unexpectedly.
