Pretty sure this "bump" is it. We hit it at pretty close to mach retard, which is probably what made it so dramatic. If I remember right, it's a little roller with a dip on the other side that you wouldn't notice at the posted speed; It's hard to make out on google. Could be wrong, never done that road before. It launched us pretty good though. Fun fun.
