Our newest member, Joy Horne Jones, took Marianna's words to "BOGO for the Challenge" to her HOA - the Oakhurst Condo Association.    Joy  put a box in her club house for 2 weeks.  She put a notice on the bulletin board and announced it at HOA social functions.  Oakhurst owners responded with generosity and enthusiasm.  The box was full at the end of the first week and still donations came in.  (And they continue!)
No special box, a simple sign, together with a bulletin board notice and making an announcement at social gatherings generated food for many meals.  Straight a straight forward and effective model. 
The Campaign Against Summer Hunger ends on May 15th so there is still time to turn-on the owners in your HOA.
