Go to the link and click on the leaf picture in the upper right, my leaves look like this. I have allot of these also but mine are on field edges and are in sandier soils but not as sandy as yours Foggy. They produce allot of acorns but I don't know if the deer use them. I also have bur and red oaks on my place and the leaves of the PIN oak look more like a red oak.
Based on the Wiki comments it may be related to the Hills and Black oak. I have tasted the acorn and it is bitter but the leaves do stay on into winter.
