No kidding!   I just looked it up on Matweb.com and the flexural yield
strength is listed at 8100psi!

The elastic modulus is about a thirtieth that of steel (1000ksi vs.
30,000ksi) , but the cross section of the tree is huge compared to
Rohn 25G ...

I'm jealous here in my little treeless backyard in MD.
