Looking at the acorns, I certainly see how you might think Bur oak, but Bur oak, being a member of the white oak group, will never have points on the leaves.
Regarding distribution, perhaps we can take into consideration the fact that oaks easily hybridize in the wild (although the white oak group will never cross with the red oak group). I am woefully inept with oak identification, however, other than those that grow in the Minnesota area.
