Small stuff sacks are great if you can ever find them in your gear(I lose mine all the time).
I use those small 6-8" long bungies to bind my extra clothes. cheap and easy.
if your trying maintain your numbers, never kill the lead sow.
if you want to kill at the same feeders often, I would only kill/shoot at each feeder once a week.
I always kill for extinction but will never succeed. they just breed too much.
