Im not sure about the cold having that big of an effect of the acorn masts. Seems to be cyclical as far as bumper crops regionally. Ive been targetting hardwoods and acorns 25 years of my bow hunting career and find that even when the acorn crop is lowone particular year, I can still find a few trees that have lots of nuts. Thats where I'll hunt and it actually makes it a bit easier to target deer for me.If I can find, acrorns, hardwoods anda creek bottom all in one locationthen its game on especially in early season when its still hot. Shade,acorns and water all close together, what more could a deer want when its still hot.
