Years ago I once payed $30 a day to park at LAX; it was in the spots directly across the curb from the gates; fantastically convenient. I wouldn't be surprised if those spots aren't even there, now, post 9/11.

That $30 then, just might be inflation-adjusted to $50, now. So anything's possible. But, like then, the $50 parking spot better be literally 50 feet from the gate/entrance. It'd be tough to pay that price to park out in left field, though.
