Travel with Intent has a weekly challenge entitled Look up Look down which appears every Thursday.
I took a few shots the other day of a jet that came from the west, from beyond the mountains going towards Verona. I liked how the jet stream seem is smoke_like, growing from the mountain itself. Here are three of the shots. The first one when the jet just came into view:
In this photo the jet stream takes on a more smokey nature as it begins to spread out:
In the third, it definitely looks like the smoke a child would draw coming from a chimney:
Have a great day, and go by to see what Travel with Intent is up to!
