I thought I was the only nut-case in the woods putting up line by the light of a head lamp. It gets really hard to find previous years scars when working under those conditions. What makes it even more fun in the dark is working around all tree tops from loggers, and the dead-fall from 2 small twisters that got us last year and that inland hurricane (we had about 25 - 30 minutes of sustained 70-100 mph winds) that dead-centered us 3 years ago. Amazingly, the maples weathered the storms better than most of the trees.
