Yes I'm petty

Hello.

A while back, I was telling some folks, Sam and others,
that the word Bumbershoot, meant umbrella. I was under
the erroneous impression that it was a word of British
origin. It apparently is not. It is however a real word.
I present to you factual evidence, ye doubting thomases you.

Bumbershoot is an annual international music and arts festival located in Seattle, Washington. One of America's largest local arts festivals, it takes place every Labor Day weekend at the 74-acre (299,000 m²) Seattle Center, which was built for the 1962 World's Fair. Seattle Center includes indoor theaters, outdoor stages, McCaw Hall, and Memorial Stadium. The name of the festival was taken from Bumbershoot, a colloquial term for umbrella, probably coined in the 19th century as a portmanteau of umbrella and parachute.

Thousands of artists, including musicians, poets, painters, dancers, comedians, clowns, disc jockeys, and more, perform at Bumbershoot in a three-day long adventure of music and art. Originally run by the City of Seattle, the festival adopted its name in 1973, when it attracted 200,000 visitors. For its first two years, it was known as Festival '71 [125,000 visitors] and Festival '72 [175,000 visitors].

Admission was free until 1980, when One Reel took over production duties from the city. The city stopped financing the festival in 1995.

So there. Nyah.
