The following was on a PGA Tour ticket in 2014. I assume it's there or possibly even something more defining that you enter at your own risk.
" By utilizing this ticket or entering onto the grounds of the Tournament you voluntarily assume all risk and danger incidental to the game of golf , whether occurring prior to, during or subsequent to the actual event, and release PGA TOUR Inc., the host site, title sponsor, presenting sponsor, television broadcasters, vendors, volunteers, Bruno Event Team, LLC, Greater Des Moines Community Foundation, participating players, and all agents thereof from any all liabilities resulting from such cases. It is further understood and agreed that this waiver, release and assumption of risk is binding on your heirs and assigns. "
