If only you were stating facts. Deer move great when it warms slightly up north when it's been very cold. For you deep south guys its probably a fairly accurate statement.
I said it’s relative.
At what point do deer start moving when it’s warmer in bitter cold? Where’s the point at which the effect disappears? When does it reverse? What data do you have to support your opinion?
obviously, there are exceptions to trends that may prove useful to someone somewhere one time. But I’m willing to bet that for 95% of folks in 95% of their available hunting time, this trend holds. Do you have people who hunt -10* weather? Sure.
