Chris knows Mid Ohio better then I do, but that can only be one of two places, and he looks to be in way deeper then I think you would be on the brakes that hard for either one. That is either near the top of the keyhole or the left just past thunder valley. I would vote for the keyhole myself.

The more I look at it, the more I think enderjetta has is right. That's the shadow from the leading edge of the fender. It does make for an interesteing optical illusion.
