Would you be able to print up some leaflets and go knock on your neighbors door, inviting them to your place for a front yard "Neighborhood Appreciation BBQ"???
(The idea being you appreciate their quiet and mannerly behavior, and you are so thankful, NOT to have nosy neighbors (lol) that you would like to throw a little party. You will be supplying the hot dogs and buns and if they would like to bring along some salads, potato chip and or dessert, that would be great!
Ask if they could bring along some extra patio chairs to sit on. If you don't have a BBQ, ask your neighbor (who you know has one) if he wouldn't mind rolling his BBQ over and manning the grill.
Have the kids blow up some balloons and tie them off with string and use them to "decorate" your yard (backs of chairs) before the regular (older) guests come. Kids will love it.
If one of the ladies has flowers in her yard, admire them and ask if she wouldn't mind cutting some for a bouquet for the table.
If people ask what should they bring, tell them to bring what makes them happy.
Hopefully all the neighbors will get to know each other better and will have a good time and thank you for the great party.
Have a few games ready. Croquet. You could have a list of games on your invite sheet . As in: Does anyone have a croquet set they could bring? Hoola hoops? Checkerboard? Or???
I can make up games at the drop of a hat. PM me if you need any long distance assistance.
Sometimes, half the fun of a party is the excitement of anticipation. lol I am already thinking of all the fun and all the new people you will meet.
