OK, I am getting weary of declining historic trees at the Exceptional Trees category. The submitted trees do have some age and size of course, being historic, but are not known for being either exceptionally large or old, which the Exceptional Trees category requires. Of course, a few trees are both known for being exceptional in size and have great historic significance and so will be waymarked in both categories.
So, who wants to start a Historic Trees category? 
If no one else does, I guess I will.
