That is easy to say when you are young and in good shape. Give it a few years or maybe some back problems, then a gas powered chain saw or other powered equipment looks pretty good. But as long as you can do it, go for it. Cheaper and makes more sense than a gym fee or tread mill.
Young? Ha! Definitely not young. In spirit, sure. But in age? No way.
Not a fan of the 2-stroke. The noise of a chainsaw in a beautiful forest is at odds with my love of nature. Now a handsaw, it's quiet, and like non-power assist in vehicles, it allows one to feel everything that's going in. In other words, I'm a glutton for punishment
