Went out to the veggie patch and came upon this mammoth! I swear it wasn't there a week ago. This is one we didn't plant so were figuring its probably a yellow crookneck, as thats all I can imagine it could be. Or not? But it's huge already!, is it still edible? The underside lying on the ground is lighter yellow. Should we go ahead and harvest and eat or is this something for Guinness world record, lol.
