I had an interesting day, wish I'd have had someone to video it for me!
I had an Oak that was leaning uphill, pretty odd in the are I cut, but it was. Dad was all freaked out it was going to come back on me. I faced it, then started the back cut, I played Stig today, the "big" saw stayed in the truck as my back wasn't up to it. Made the backcut on one side (25" tree with an 18" bar) dad was really freaking out now. I walked to the truck, grabbed two wedges and a hammer. Went back, stuck one in, cut on the other side, stuck it in so it wouldn't setback on me and set the hinge. Dad about crapped his pants as I used a 16oz (yes, 16oz) hammer and made it drop where I wanted it.
Then I had a good screw up, yes I admit it!
Standing dead Oak but there was a rats nest built up around the base. Rat or Possum, either way I didn't want to play with a pissed off critter! I made the face, damn nice face mind you! BUT!! I went to low with it, then the backcut was way too high! I wedged it over, but certainly not something I was proud of! I screwed up and learned from it! 
Everything else was an ALAP, I didn't want to leave wood behind!
