The replica town, which includes a jail, barber shop, hotel and saloon, shares its name with Dale Earnhardt Jr.'s bar in Charlotte, N.C. - Whisky River - and is used by Earnhardt's production company Hammerhead Entertainment.
With his salary and winnings at $14.9 million and endorsements of $11 million as of 2014, Dale Earnhardt Jr.'s net worth is estimated at more than $300 million.
