Yes there are days like that but it's early. Keep hammering on them, it's gonna get good before long.
I hit 3 of my spots this morning and not a single gobble. 35 degrees, clear and no wind, figured they would have lit it up. I seen one hen by herself yelping her head off and chasing crows around. No gobbler with her and nothing responded. I'm guessing it's a little early and they just aren't as anxious as me.
