Before i leave L.A. i am going to try to get to the top of the U.S. Bank Tower. it is the tallest building west of Chicago, and the tallest building in the world with a Helipad on top. it is designed to with stand a 8.3 earth quake. I am not sure if they let people up there or not. I have searched the internet and can not find out if they do tours or not, but i am going to do it if they do. If any one knows if they do please let me know.
