And the cabby is unaware of her year long disappearance. He has no radio, no tv and doesn't look at newspapers. Right? Her picture has been plastered everywhere. Her thick, full, dark hair would help make her easy to remember. She has been shown with her hair up, down, pulled back, full and frizzy, and full with wave. She's even been shown with short and blonde styles. Why wouldn't the cabby contact the police to say he picked her up at x and dropped her off at Z?
Because she did get a ride to the park -- but not in a cab.
Oh I still think that Condit is a strong possibility, but am also examining what other explanations are out there.
