Helping with local car show. Looking for advice/ideas

Thanks all. Im not sure what my role will be but I figgered I would ask for advice here as I would like to positively contribute to the show. Last year if i recall they had over 200 + cars. Grows every year.
Like I said whether its serving wobbly pops or parking the entrants or petsonal tours for the ladies it will be fun!
Anyone got ideas for games? Keep in mind its father's day.
Thanks again!
