I've had offers like that several times in the past, and I took them up on it!!Two years ago I had a bumper croup of squash and tomatoes.
After a couple of months of freezing, canning, drying, cooking I had had enough LOL so told about 5-6 different people that they could come and get anything they wanted out of the garden.
I did not have a single taker
We have some friends who live in the northwest that belong to a group called Gleaners. They pay a small fee each year, and get together to glean the fields of leftovers, and also do pick-ups from certain stores.
It means a lot of food is not wasted by using just a couple of hours of their time.
