I am sure that it was a scary situation, but accidents will happen. We just try to limit how many happen at any given time. It is hard to control a saw doing the type of cuts that you are doing, plunge cut's is an art. I Knew a builder who constructed houses 'off grid' and he only used chainsaws in his construction; every cut was via- gas saw. Dad was a HVAC guy and traded work out with him for his barn. that man cut many perfectly square holes for ductwork and air registers. I was amazed!! He would show up in the morning with a butter biscuit and beer in hand and as the day went by and several beers later, his cuts became more precise. I told Dad that if that man didn't drink, he would have to retire.....
I am glad that he will be alright, he will have a cool story to tell for the rest of his life. Whew!!
Neighbor's, sounds like you have some of the coolest around. Makes me happy that you will have them there when you move. Most people will not find this in other locations. I like to think though that rural America "Trumps all other locations". Its not just the land we like- its the people as well.
House is looking great!!
