Deer are survivors! It takes more than drought to harm the population. We are lucky here in N/W WI, we have had enough rain to keep things green. I have hunted many years when it was drier than a popcorn fart, we still had plenty of deer, they just adapt to whats available and eat more in the woods. I have seen deer drink from my stock tanks out in the field. Deer and elk will do this out west as well as the prong horn.
