Fair points. After about 75% you can stop reading Atlas Shrugged. I just found the whole idea of the railroad, and the battle between Mooch, Boyle, and Jim Taggart, versus Dagny, Reardon, and Eddy Willard to be fascinating.
Agreed, Fountainhead was the first book I read, thouroughly enjoyed it. Atlas Shrugged, I was looking forward to bury myself in it, but it was hard to finish.
