The plastic almost disposable clear plastic umbrella is genius! You can hold it low and still see enough to avoid collision! Which is pretty important in CROWDED urban areas. Looking through one is a little like a car's windshield with out the use of wipers. There are even public set-ups where you can grab-and-go-use-and-return! Perfect for the rainy season…which can catch you in a sudden downpour. History of the plastic umbrella.
