re: Sweet potato planting for ducks

Back when ducks were plentiful in SWLA we hunted flooded sweet potatoes and killed like crazy. My dad would take two weeks of vacation during duck season and we would hunt the same blind every day for two weeks and would shoot easy limits every hunt. You couldn't run them off, but again, ducks were very plentiful. I'm talking 50's to early 70's. I always thought it was the vines they were interested in.
