Yep, that hill that I've affectionately named "pucker hill" was due to the fact that on the way down/up that hill in the background, the X was very high camber (i.e. slipping, uneasy "tip/roll" feeling) and also where Frontier Gary popped a stock skin on some gnarly rocks...
If you were sitting IN the X, you'd be looking at the "Jeep Hill" out of the windshield (that is, it's not in the picture).
