While this books covers an awful lot of ground I am going to punk the author for overlooking something I think is important, and I am sure, that the author (as a "teacher of history at the US Naval Academy") does not. He delves into America's cultural periods and more or less draws defining lines, events, lives, and trends. But once he gets to the 1960's he takes a big "duh" pill. While earnestly covering the Acid Tests an Ken Kesey's contributions to "American fun' he overlooks the longtime surviving cultural fizz from that froth, that is, the phenomenon of the Dead Heads. surely, the continuation of the grateful dead's musical career over five decades of American history must count as something as worth Beckman's notice, eh? Mais non. After all, "DeadHead-dom" survived alongside and symbiotically with the band, and even today, exists in those places where the band concerts and Dead freaks congregate, sans Garcia but as strong and tight as ever. Perhaps the erstwhile cadets at Mr. Beckman's school could come up with some appropriate prank to set him back on his stuffy academic butt? I am sure they could think of something.
