Oh, that discrepancy always gave me the creeps too.

My friend spent all day proving some celeb was just buying groceries, not hiding a baby bump.

Ever wonder what the ground itself is made of out there? A lot of that 20 foot shift happened along the actual fault line, like a clean tear. The land on either side just slid past each other. If that same movement happened under a city block, yeah, total ruin. But in the hills, it just redefines the landscape.
