Isn't there already some type of Hunters Feed the Hungry program in WA where the hunter(s) donate all or part of their harvested birds or animals to various food banks? Although it'd be great for a program like you suggested, it would be a nightmare for FWP to enforce and we all know that some hunters would take advantage and keep both animals they harvested. Just my worth.
