From Salem, Oregon - Department of Community Services:

Through local neighborhood associations (recognized groups affiliated with the City of Salem) we are offering to support neighborhood picnics, parties, celebrations held on 9/16/07. We developed a menu of services from which the associations can select, including:

  • Up to 100 printed invitations with original art from a local artist
  • Additional picnic tables and garbage cans if the event is held in a City park
  • Recreation staff to lead games or just the equipment to check out
  • Party Buckets with bubbles, sidewalk chalk, etc.
  • A basket of kids books with a "neighborhood theme"
  • Up to 100 ice cream cups (yes, with the ice cream)

We just announced the idea and already have a half dozen events being planned.
