Whenever the temperature in San Francisco pushes past 60 degrees you may see them. The Eager to be Naked Beaver lives for any opportunity to be bare in public. The athletic males remove thier shirts. The hairy, free spirits remove everything but their puka shell necklace. On a sunny day, female Eager Beavers (a bit more rare) can be spotted wearing a bikini, laying on any patch of grass larger than their beach towel.
