I spent one long afternoon walking along the Niagara Parkway from Dufferin Islands to the Tesla statue by the Victoria restaurant (or whatever it is called these days). It was a week day so the tourists were minimal. The air was crisp and clear, little wind to blow the mist around and the bright sun to dry out the clothes. There were a few spots I stood where the rush of the river was so loud it drowned out all thoughts. That alone made the day perfect.
I sat under the tree right here, my favourite tree, and actually wrote for a while. There were lots of problems with the story but that day I remembered some key elements about my characters. I let the fresh air and scent of the water fill my soul while my brain absorbed everything around me. I made two pages of notes on the setting. Silly, really, because this story never goes near the falls but the connection to nature is very strong, elemental.
It is good to take yourself out of the routine, hie off to a change of scenery. While it might be familiar, you never know what you might find. I found peace, the germ of an idea, and wild yarrow growing at the edge of the falls.
