Any ideas for an outdoor picnic or b-b-q for our Church?

I am planning an outdoor event dedicating a new playground for our Church...I'm thinking around Fathers day so we could incorporate the two. Maybe a Picnic/ BBQ... any ideas for a menu or fun activities that would get the adults and little ones involved? I also need a catchy title for our bulletin. So far I have 'Burgers,'Dogs, and Dads...not the greatest I know..Its my first big project as new CE Elder and I'm very nervous, I want it to go well so ANY suggestions would be greatly appreciated!!! Thanks
