Happy "birthday", Sierra Club!

The Sierra Club is one of the oldest, largest, and most influential grassroots environmental organizations in the United States. It was founded on May 28, 1892, in San Francisco, California, by the Scottish conservationist and preservationist John Muir, who became its first president.

Well done, John Muir.

This is my membership card, the best I can do today....the weather is rainy and I'm feeling under it, so this is my "birthday" challenge entry.
