Give a guy a wind checker & a compass and he goes nuts! [8D]

I’ve always noticed this ever since I started paying attention to wind. It’s REALLY been killing me at my house the past couple outings cause I’ve been on the ground. Wind blows from the SW for 15 minutes, then blows from the NE for 1 minute…repeat. I’ve seen it at my main hunting spot for years. Its not a swirling wind, but a back & forth.
