yesterday I was taking down a 24" DBH red oak that was 6' from the house with a little backlean toward the house. Got my 3 wedges in and realized that I needed another one - NOW. Reach into the pouch and nada...quick sprint to the gear bag 20' away and alls well.
That was a seriously scary experience - the guy on the pull rope 100' away says "Gee, your face looked kinda red, what was up?" It was his house so I didn't want to tell him that I was thinking about how close we were to an insurance event
Lesson - one the larger trees where proerty is at risk keep extra wedges in every pocket you have.
