It is the springtime. Spring fever has hit.
This is not unlike when in the animal world, the grizzly bear comes out of hibernation and craps all over the place to mark his territory.
Except here, folks fling their poo at each other instead.
Springfever anmial instincts - that's all it is. In a week or two, some folks will be shedding their winter coats and malting. I'm just not looking forward to mating season this year -- with the long winter and rainy spring, it's gonna be a mess to clean up this place!
If you are familiar with the signs of the turning of the seasons, you wouldn't be surprised by what's going on here...
