New U.S. Record - $175 Million

If rumors and news reports are true, then the sale of the Steve Forbe's Trinchera Ranch in Colorado for $175,000,000 has just set a new record.  The 171,000 acre property was purchased by billionaire hedge-fund manager Louis Moore Bacon and tops the $103 million Ron Baron paid earlier this year for his Hamptons tear-down.   

This comes only days after Saudi Prince Bandar bin Sultan takes his $135 million Hala Ranch off the market.
