I have supported our local food back for over 50 years, even being on the board way back when. A community food bank not only helps those in need now but others who for unforeseen reason may need it in the future.
Part of prepping should include support of your food bank.
As well as cash or surplus crops, you can rotate your end of best by date foods and replace with fresh.
There is the added bonus of a viable community food bank that when a SHTF event occurs there will be reduced pressure on people coming after your stuff.
Thanks
