    I had a stick of 120' of Rohn 25 guyed every 30' up with Philly.  A 
large, previously thought healthy maple went to ground due to wind & 
rain. The maple took out the eastern guys at 30' and 60'. The tower 
remained up with a serious wow just below the 60' level.  Seemed fairly 
stable and I gave transient thought to going up it to save the antennae 
on top. I discussed this situation with a group of experienced tower 
fellows and promptly dropped the tower without another thought of trying 
to "save" the antennae.
    I was also surprised that the tower would have remained upright with 
such a force applied but , in the cause for safety, it really didn't 
matter.  I've been harvesting the sections when time allows for scrap- 
not for rebuilding purposes. I would not trust any of these sections to 
be good after the hula dance that they were subjected to.
     73 and I remain,
