More will follow.
It's the last helix before the final break run.
On the left hand side.
Near the end of the ride, the train will hit the brakes, you'll get some massive positive Gs as the train releases from the brakes, a flip over turn, a helix, then the cameras will appear to your left.
Don't worry, just hold up your hand, look at them and wave. It will be a perfect picture. I have one on my nightstand.
No problem if you get it wrong, just run up the queue and ride it again. Be at the gate early so you can get many rides before the crowd arrives. Front seat is a must. Run to the Hulk in the morning and get your Front Seat ride, then try the back row.
Then Spiderman, Dr Doom, then Deuling Dragons.
