Windstorm.

Yesterday, my greenhouse blew away. It didn't get very far; across two backyards (counting mine), across the street behind my house, and into the alley between two garages. Not far away, but dragging it back home was a workout in itself! 

I spent this morning setting it back up and anchoring it a bit better. Hopefully it won't be going anywhere now. It also now has a floor! :)
