When the tree starts to fall get the heck out of the way quick. Clear an escape route at at a 45 angle to the tree.
They call those widdowmakers for a reason. You also want to look up into the tree beore you fall it to see if there are any dead branches, lose branches, or branches caught up in other trees.
Yup, did all that, I just was not expecting another tree to throw something my way. The delay was what caught me by surprise, the tree was completely on the ground before the missile from the other tree landed 3-4 seconds later.
