I also suggest you click the 'Compare to this version' and use the 'side by side' comparison in the box on the left. Makes seeing what was chaned really easy. It's still very long and very complicated. If you read everything it applies to, it will take you quite a while. Do you actually think all the legislators that will vote on this will read the whole thing and the laws it refers to?
