I think you letter is great! Perhaps you might talk to the local farmers in your area also.
Before my parents passed they lived in a neighborhood that was mostly for the elderly in California living on fixed incomes.
One of the local farmers, would come by and leave a hay wagon at the entrance to the development every Friday.
This was meant basically for the residents, but anyone was welcome. The wagon was full of all types of fruit and produce he didn't sell during the week. It was better than throwing it out. The fruits and vegetables weren't spoiled just at or past it's prime.
The people only took what they needed.
Too bad others didn't do the same. I know that farmer has an elevator of his own to heaven.
