The company I work for likes to give out free baseball tickets to employees.  In addition, they would like to use the company bus/shuttle to transport folks to and from the game. 

Being in HR, I don't think it's a good idea.  I see lots of risks and liability.  However, the President likes the idea.  I need to convince her otherwise.  How would you approach the issue without sounding like a party pooper? 

Thanks
