Wind ruined my sit tonight. North/Northwest by forecast 5-10, temps dropping well below zero. Pop-up blind 140 yards N.E. of the road kill deer. I put the ecaller on an old auger straight west of me 30 yards. 5 coyote have been staying along a tree line 1/4 mile s.w. of the bait. Their on a different property owners land, they won't let me in(son is hunting) or I would kill them during the day. As they sleep in same beds often, with N.W. winds and sunshine. I played prairie dog(none within 300 miles) distress, low volume. An owl was first, then 4 of the 5 after I heard them assemble call about 250 yards west of me. I muted the call when I saw them with the Leupold thermal. They looped S.E. around the pasture corner fence, started to the bait. I waited, watching thru the thermal. The deer hasn't been opened up yet and they only appeared to be checking it out. I got the rifle/Wraith ready, before I could shoot a couple of them looked my way as the other two trotted away. I then noticed my breath rising up and out the blind window. Checked my NOAA weather wind map on satellite, it showed a cross wind. But when I left the blind, I noticed the wind was swirling around the grain bins behind my blind. And seemed to be N.E to SSW.
