bocat scent in frost?

[wablkandtan]

found a couple tracks in heavy frost the other day and the damn potlickers couldnt smell anything. Has anyone else had this happen. i figured it would be just like snow but my dogs have no problem in the snow. what the deal with the frost?

If u hunt at night & along towards morning the frost
is falling,
dogs can,t smell vey good,
But then after daylight & temp is going up & frost is melting off , dogs can start smelling good again.
