My son and I will be going to a Orioles/Yankees game in like aug or sept. I forgot when but its our companys employee day thing. So beings this is my first time going to a MLB game what is there to do. Like do players come out and sign balls and how is the best way to ask them if they do.What kinda pen is good on a baseball. I have no clue as what to do as I never been to one and want to make it as enjoyable as I can for my son thats 7. I am not looking for the Arod or jeter autos. Anyone that would sign I would be grateful to them just to have my son enjoy it. Also can you take a DSLR camera with you in to the park? Any other suggestions I would be grateful.
