Put someone in charge of the menu and RSVPs, ask someone to plan the activities, ask someone else to arrange permits and someone else to schedule entertainment and logistics like renting tables and chairs. Make sure everyone participating is listed on the invitation. You may also want to call some people who will get behind this and make sure other neighbors attend. List them, too. The more, the merrier.
Summer is cook out time, and the living is easy.
Use a BBQ design to decorate your tables. Choose from table covers, plates, cups, napkins and more to pull through your theme. You don't need much more than that. Hamburgers, hot dogs, chicken, baked beans, cole slaw, potato salad, cold pasta dishes, corn on the cob, apple pie, chocolate cake. A good old-fashioned BBQ menu.
