I spent 4 days in the 'horse capital of the world,' where the barns look more like estates and billionaires convene for the world's largest horse sale. Here's what life looks like in Kentucky's second-biggest city.

• Lexington, Kentucky, is known as the "horse capital of the world."
• The region is home to about 450 horse farms as well as Keeneland, the world's largest thoroughbred auction house.
• Lexington is also known for its bourbon and has its very own trendy "Distillery District."
• The median listing price for a home in Lexington is $245,900, but houses in more upscale neighborhoods can range from $750,000 to $6.5 million, according to Riley Kirn of Bluegrass Sotheby's International Realty.
• I recently spent four days there - here's what it was like.

Earlier this month, I flew from New York City to Lexington, the second-largest city in Kentucky.

Lexington, home to about 324,000 people, is known as "the horse capital of the world." There are more than 450 horse farms in the area, as well as the world's largest thoroughbred auction house, Keeneland.

I spent four days in the northern Kentucky city, and it became clear that life there revolves around the horse industry as well as, of course, bourbon.

Here's what it was like.
