Yesterday got busted by not checking the wind correctly. Going by pic which shows my simple wind string which is still and just hanging straight down. I was at heavy brush ground stand and did not take into account evening cooling going downhill even thought we are only taking a 6ft slope between me and pig. There was still perdominat calm to me West wind that had my my scent going straight to the pig. I watched the pig just show up from heavy cover and as soon as it hit my scent it turned and ran. It clearly snort grunted several times when leaving telling me you goofed !!! Lesson learned!!
