RE: Drought and acorns??
There seems to be a normal crop around here and it's been really dry. I would try tohund a funnel if you can. One of my best stands is in a white oak inside a funnel. That way in a season with limited food, they'll come for the acorns, and the other seasons just to pass between beds and other foods.
I'm planting some persimmon trees on my land this year. I've noticed at my work the deer go crazy for those things.
