How much is a trillion anyway? Pretty tough to get your head around just how big a number that is.  I heard a great visual analogy the other day (someone had attributed it to Ronald Reagan).

If you have $1M in the form of a stack of $1000 bills, it reaches about 4.3 inches high.

How high is a stack of $1000 bills enough to make up a TRILLION dollars?

Over 66 MILES high.  And since last September/October we have added nearly TWO TRILLION dollars to the national debt, that stack is 132 MILES HIGH

Holy deep guano batman!
