This is one of my favourite shots from my trip to Alberta in 2013. I was with Scouts for the Canadian Jamboree and it was incredible being able to see the fields and plains continue on forever, with no mountains to obstruct the view. It just so happened that there was a rainbow and a nice shot of the storm over the field in that direction.
I was on my way home from work one day and I happened to look over behind me and saw this view. The rain in the distance looked cool and it was an interesting perspective to see rain from. You can see the way the wind moves the path of the rain as it falls from the sky and where it is heavier.
