Thank you.
I have trouble telling the difference by just the leaves and forgot to note it at the time.

correction
sorry, I was thinking red oak (Q. rubra) which it is not but more likely it is Shumard Oak (Q. shumardii) which can also be called red oak. A leaf characteristic for the species is that the sinuses are almost tear-drop shaped with the lobes almost touching, whereas the sinuses in black oak are a wide-mouth "U" shape.
