For the hay set you don't need left out bails . For the hay set you just spread some hay around in a small circle make small pile in middle ( put bait or lure ) and place a trap on each side. I us this set almost anywhere . Middle of woods, fields, old tram roads, ect. the hay is eye appeal .
If I had any pics I would post one to show you what I mean. Maybe Hern or Renny can help out .
