interesting and inspiring response Boobearsmom!
This reminds me of years ago, when my family lived in a 40-unit apartment complex where I was assistant manager.
We had regular blockwatch parties in the central courtyard with a big BBQ and pot luck dishes. We invited a few law enforcement officers to speak about ways for keeping our neighborhood safe. A D.A.R.E. officer addressed the youths about staying off drugs, out of gangs and staying in school.
In addition to everyone bringing a food or dessert dish to the party we asked all the neighbors to bring as many coolers as they had and we filled them with ice and soda cans. We placed several empty 30 gallon trashcans around the area for trash and some designated for the cans (cut a hole in the lid and spraypaint "cans only" in a contrasting color). At the end of the party all the empty cans were collected and added to the regular aluminum recyling bin. The funds from trading the cans in were used at the next party to purchase paper plates, napkins, plastic cups and forks etc.
