A few more:
The township/county shop has you on speed dial when they remove trees in the right of way.
You know the new and/or used saw inventory at the local shop by heart.
You know the average shelf life of a used saw by model at the local shop. (ex.: 044/440 sells under 1 week, rarely 2)
You get free biology lessons from nature about all of the fun critters, such as the ground hornets living right under the 3 yr old oak blowdown, and finding out what a milk snake is after find one inside of the rounds as split them, etc.
You wonder why someone would ever pass on piles of cull logs/butt cuts that you eventully get 10+ truckloads from, even though you had to hack through 5 ft high stinging nettles to get to it, find snakes the fun way in the pile, and get this stuck and wraped around twice in one of the knuckles on the front drive shaft of your 4-wheeler:
and have to borrow a power inverter to use a dremel tool to cut it out in the dark after driving your truck as close as you dare to the 4-wheeler.
You consider an old manure spreader an excellent wood trailer.
