As a result there won't be a lot of pics in this thread, which is a shame because the blood trails were both educational.
I went to the same stand I was in 2 weeks ago. The feeder went off and nothing was happening so I got down and went to another one that I knew had not gone off yet. Before I got anywhere close I could hear the squealing. The wind was howling so I could get away with a lot. I was about 30 yards out when the feeder went off. I was able to cut the distance another 10 yards. There were 2 sows and 7 pigs about 20 lbs apiece. The sows were both dry.
I made it another 5 yards and then waited for a shot.
