Why did I pick these books (3 of 10)?

For lack of a new Paul Theroux travel book - I have read all of them - I have chosen one by Bill Bryson. This is the only non-fiction book in this bunch of 10. One in 10 is about the ratio at which I read non-fiction books, usually travel books. Some of my other favorites are Redmond O'Hanlon, Eric Newby and Wilfred Thesiger, i.e. all those writers who survived tough travel environments. However, Theroux is my favorite because I admire his style of sarcasm.
The Lost Continent is not the first of Bryson's books I am going to read. Earlier I read A Walk in the Woods to inform myself about long-distance hiking. If you happen to be in hiking long trails, I recommend you to walk along the former demarcation line between West and East Germany. Strangely enough a travel book has not yet been written about hiking there.
The Lost Continent is one of the lighter and more humorous books in my list of 10, so I expect to read it quite early.
