Style in "Two Innocents in China"

I was wondering how Hebert and Trudeau were going to handle the grammatical quandary of having two authors writing a travel book (something that is usually a solo experience.) Since they would be experiencing different things and talking to different people, surely they couldn't use the collective "we" for the entire length of the book. I assumed they would be resorting to a fully third-person narrative, as Carl Bernstein and Bob Woodward did for "All the President's Men." Instead, they found a perfect hybrid, using "we" for instances in which "we" is appropriate, and last names when someone is being referred to specifically. It's really rather a simple solution, but one that I would never have thought up myself, and it works seamlessly.

On another note, the book is filled with gems of historical knowledge that are alluded to in throw-away lines that make any reader able to catch them feel sufficiently smug and full of self-worth. References to Bourassa and the Social Credit party are gifts to the reader, who feels proud that he remembers Grade 10 Canadian History.
