In anticipation of my visit to Springfield next week.

Still not sure if I should have waited until after my visit to Springfield to read this, but it's too late now.
It's not on the level of Confederates in the Attic or Assassination Vacation (he can't bring the funny irony in the way that Horwitz and Vowell do), but it's a fascinating look at the ways in which people have used Lincoln to suit their purposes. His review of the new museum made me wish he was a bit more of a museum person, but I did appreciate the backstory to many Lincoln sites.
It should have been more, but it's pretty good for what it is.
