I am fortunate to live in a part of Calgary with established trees and pockets of green space.  It’s a delightfully walkable and bike-friendly part of town, and between my commute, my garden, the playground and the tobogganing hill, I spend a lot of time outdoors.  These trees are old friends.  Sadly, many are falling to age and development;  still, saplings are planted to replace them.  Life goes on.
