Empty milk jugs written on with a paint pen, put up by the can recycling area may be a way to collect them. That is how we save them. I think it is a great idea. No clue how best to advertise this idea. I believe you could bet a great quantity of them collected during that time! Possible check about posting something in Joannie's food wagon (I know her well) and some of the other ones. I have a handicapped child as well, and an grateful for help I have received in the past. Getting something like this going would be awesome! Let me know if I can help!
