I am reading River of Doubt by Candice Millard. http://bookmooch.com/m/s/the+river+of+doubt+theodore+roosevelt+darkest+journey

It's an account of Teddy Roosevelt's difficult journey along an unmapped rainforest river with his son Kermit, many laboring South Americans known as camaradas, and famous Brazilian explorer Candido Mariano da Silva Rondon.

It's fascinating to read what this elder statesman did to challenge himself after losing his last bid for the White House to Wilson.

You will definitely enjoy this armchair travel from the comfort of home without insects and waterfall rapids!
