Query: A biker with an attitude

The author is candid about his personality quirks which made him bad company for his two riding companions on his trip down the length of the western hemisphere. Well, I'm sure they were all under some stress. But bearing up under anxiety is to display grace under pressure. Actually it's a change to read an adventure memoir where the author isn't a paragon of heroism. Also he doesn't leave out his adventures in the boudoir.
