I am heading out to the Roughrider game today.  I am taking my 6 month old son to his first ballgame and we are going to sit on  the outfield grass.  My question is do I have to buy a ticket for him?  The ticket phone # number to call does not answer on the weekend and I do not want to have to drive up to the ticket office.  I buy my tickets from Kroger, so I can get the ballpark hotdog as well. 

Thanks for the help, hopefully it will be a great day for baseball!!
