James, Spread is certainly worth recording and the giants of the eastern forests represent one more max dimension we can track. But as Don says, spread is treated in big tree lists and a subordinate attribute and is not so clear to measure in a meaningful way. Measurement is not that hard, just time consuming. It is likely not as repeatable as is height or girth by different people measuring the same tree. This is a "muddy" dimension with no clear easy methodology.

Will, If they are tedious for you then I am gonna have fun learning...ugh.....but yes, I can see spread is harder to do. I figured that most sites probably would not benefit from having a RSI but Congaree might be one exception.
