PGA Tour Player Fees: What Do Professionals Pay to Play?

Question
Do PGA tour professionals have to "pay to play" golf at each PGA tournament they play in?

Answer
Dear Larry, thanks for the question.  Yes sir...greens fees and pull carts.  Just kidding.  But yes, the players have a nominal fee relative to their potential earnings, of $100 per tournament...more of a registration fee than anything.  And of course, above and beyond that is paying their caddy, travel, and often their's caddy's travel, room and board...etc.  Thanks again for asking, good luck and remember...

Love the game,
