I found this in a local strip mall and I was able to reach some acorns but I am not sure exactly what it is. At first I thought it was a bur oak, but the lobes are not deep enough even though the bark looks very similar. The acorns are about the size of the end of your thumb from about the first knuckle forward, so I would not consider them "big". Tree was roughly 30 feet tall or so. Seemed to be doing just fine in the strip mall setting and I figured it might be some sort of of specialty oak as I am sure it was planted and NOT there by mother natures hands. I'm pretty sure it's a white oak of some sort, but other than that it doesn't fit the other oaks I am familiar with that are native to my area.
