Red Oak

I'm not totally sure of my Id's on these (and especially the last leaf) as the Red Oak is similar and in size and width to the Black Oak, and only slightly thicker than a Pin Oak -- and shorter than the Southern Red Oak. Beyond that, the Red of the Red Oak (and the Black of the Black Oak) is not about leaf color, but about wood color... so any guess based on Fall color is secondary.
Of interest: The last leaf looks more or less symmetrical, but a quick look at the vein structure showcases a common attribute of oak leaves, alternating vein branches.
