Thanks for the recommendation - and I'll have to check out "Where the Buffalo Roam" too.

Regarding the 1972 election, Timothy Crouse's "The Boys on the Bus" (published around the same time as HST's book) is also worth reading. It's about the reporters on the road reporting on the campaign ("one of the first treatises on pack journalism" sez Wikipedia) and includes various colorful characters, including of course HST, who also wrote the foreword.
