Sometimes, after a snow, the weather warms up a bit. The warmer temps and the shining sun causes the snow from rooftops to melt slowing and create huges icicles. It's hell on the gutters but it sure is pretty to look at.
This corner in the spring and summer is a hot spot for protests and demonstrations. There are usually people with flags and banners waving at the cars that go by. I guess this apartment dweller decided to join in.
