ENTS,
 
Today I found a large, but not champion-size, Scrub Oak. It may be the largest I've seen, but I don't know for sure.
 
One of the stems seems to be about 6 inches in diamater, and it may be 8 or 9 feet tall.
 
I found the national Champion online. It's in Shenandoah in Virginia, and is
41 feet tall, 49 inches in circumference, and has a 34 foot crown spread. I can't even imagine a Scrub Oak that big. Anyway, what I found is still pretty big. And Scrub Oak is very common here.
