Games for Picnic

I do not have children so I was wondering if anyone can bring some games / activities for all the kids to share in?

Does anyone have anything that we could hang (some type of banner) for people to find us easier?

Thanks to everyone who is assisting with the picnic. Please feel free to still sign-up OR show up for the picnic on Saturday from 12 - 3 at the Catty Playground!!! It is the new pavilion by the tennis courts and the sand volleyball courts.
