The Explorers Club has to be one of the coolest membership organizations in the US. Founded in NYC in 1904, the club supports scientific exploration of every corner of the globe – and space. Club members hold many of the big “firsts” of exploration, including first to both poles, first to summit Everest, first to step foot on the moon, etc. There are many categories of membership at the club – and I can think of no better way to support these worthwhile endeavors while spending time with supremely interesting people than by becoming a member of the club. Details here. I’m keen to join myself!
