Oregon is the Webfoot State and the citizens are Webfoots, because of the rain. Oregonians don't tan - they rust! It goes back to around 1862. Legend has it that a visitor staying with a family on the Long Tom, a tributary of the Willamette River, was so disgusted with the soggy weather that he remarked all Oregon children should be equipped with webbed feet like a duck. "We have already thought of that," said the lady of the house and produced her baby - who had webbed toes!
And it hatched out a sports team - the Oregon Ducks...and some, ahem, rhyming war cries from their opponents the Oregon Beavers.
