The Curious Case Of The Trash Can In The Wind Storm

I have a limited, sophomoric understanding of physics. But what happened last night seems impossible. The wind was strong all night. A great, unseen staccato of gusts shook the house, flickered the power, and moved my trash can. But not only moved it. Guided it through a Borgesian labyrinth to the front of the house, nestling it in a cement corner of the house and steps.

I have drawn this phenomenon to scale, with the Trash Can represented in light blue, and the two possible paths in black and yellow:
Now the black line is the course I believe the trash can took. The yellow line represents the more plausible course. However, this feels more implausible when one considers the dynamics of navigation required amidst the wind tunnel between the two houses, the degree of the right angle and lack of space between the two cars. However, the black line is also unlikely given the fact that the gate (two barn-type, shoulder-length doors), represented in brown, opens towards the cars and the space between the red car and the house, while enough exists, hardly merits the likelihood of successful of travel without setting off the car alarm.

Yet it did happen. And I, in my socks and t-shirt and jeans, pondered it at great length in the aria of wind singing around the house this morning. I traced the possible paths while holding the Trash Can. Measured the breadth of passage between all the necessary straits...

It is indeed a most curious case.
