I was fourth generation in the family. When I was a kid my Dad, his Ex FIL,1 BIL, my Uncle and his SIL were all Licensed Arborists that owned their own business. I never knew anything else. When Dad retired in 1986 I gave up the family business. I was almost 30 years old and had worked 3 years without taking 1 day off. Even weekends were spent giving estimates. I went to work for UPS where I eventually got 8 weeks a year off. But, I still loved climbing and continued to climb as a "Contract Climber" for other companies. Finally gave up climbing at age 60 when I had both knees replaced. My wife says I can't be lived with if I don't run a saw for an hour aday. I have about 70 chainsaws, most over 70CC's, a dozen over 100CC's, couple years ago I bought a Brush Bandit 65 chipper to keep the invasive species under control on my 30 acres. My wife is correct, I'm happiest if I can step out the front door and smell fresh split Oak firewood, milled Poplar, or chipped Pine. At 66 I can't think of what I'll do if I cant use a chainsaw, even if it's an ikle MS170.
