Let's make this birthday one to remember.

66 years old (Born on July 05, 1958)

Happy Birthday, Chris Cline! You're the only coal executive we know who can truly say he's "mined" his own business into billions. With your keen foresight (pun intended), you've turned lumps of coal into mountains of success—proving once and for all that being on Santa's naughty list isn't always a bad thing.

From humble beginnings to becoming one of America's most successful entrepreneurs, your journey has been nothing short of inspiring. Here's hoping this birthday brings you as much joy as discovering another billion-dollar reserve. Keep fueling those dreams—and remember, age is just a number; net worth is forever!
