The Lost Symbol by Dan Brown

Just finished this book by the author of The DaVinci Code. It was an exciting read, one that I am sure will make a good movie (watch out ). It was definitely a whirlwind trip through the city of Washington D.C. and had the bonus of all the interesting secret stuff that is alluded to about the Masons. I find all the conspiracy stuff interesting because my dad and most of the older male relatives on my father's side of the family were also Masons.
Reading a critic's view of the book, it seems that Brown got a lot of geography and architecture wrong. With so many ways to check these facts and the inevitable way some people are such sticklers for detail it would seem he would have done better homework.
