Found this one via Snapple real fact #462: The King Ranch in Kingsville Texas is bigger than the state of Rhode Island, and over 23 countries. The 825,000 acre ranch even has a web site, and according to it:
Based on the national average of 70 pounds of beef consumed per person per year, the 60,000 head of cattle on the King Ranch could feed a city of almost 5 million people for a year.
and
It is a shorter drive between New York and Philadelphia; or Pittsburgh and Cleveland than it is from one end of the Ranch to the other.
and
If you extended the fencing on the Ranch end-to-end, it would stretch all the way to Boston.
