Jeff,

Your post reminds me of this Motown classic:

Like a snow ball rolling down the side of a snow-covered hill, it’s growing.

Like the size of the fish that the man claims broke his reel, it’s growing.

Like the rose bud blooming in the warmth of the summer sun, it’s growing.

Like the tale by the time it’s been told by more than one, it’s growing.

Every day it grows a little more then it was the day before.

Somehow I expect the number will not be an even $500 million. That would imply an element of guesswork in the calculations of the well-trained government planners.
