now we know why

Galiano Island honors Spanish explorer, Dionision Alcala Galiano, who sailed in an out of the Gulf Islands off the coast of B.C. in 1792. He would have felt quite at home gazing out to sea from its sandy shoreline. The same molten sun smolders there as scorches Seville on a hot July afternoon.
To get to Galiano Island though, in the midst of summer, you must keep green coastal forests and salty breezes fixed firmly in mind. There's the gauntlet known as The Ferry Terminal....Doesn't terminal have an ominous note to it? Terminally waiting....
Ferry Terminals are acres of asphalt.
Cars simmer in the sun. 
It's solar heating gone wrong.
People melt out of cars and trucks and motor-homes and draw a bead on a distant patch of shade the size of a small tablecloth. 
Dogs come too; every size and hairy, tongue lolling variety.
Man and beast.
It's close quarters in the shade at Tsawwassen Ferry Terminal on a July afternoon.

A group dropped to the grass near our feet. They lolled on backpacks and leaned on bags. Their restless dog turned around three times as though looking for something he had misplaced. Where was his bag? Oh, there it was. He lifted his leg and sent a steaming stream into the purse of his mistress and down her arm which was resting protectively over it. 
Who shrieked first?
We had noticed the grass was still pretty green there, near the tree.
Now we know why.
