Even if the owners are selling little 'firewood bundles' at $10/pop in supermarkets, with the sawdust to pellet makers, the good hardwood pieces to artists, and have a wood stove, and do whatever else with the other scraps..they still probably barely cover their overhead.

I'm not sure what a bucket truck costs, but with all the additional hydraulic gadgets I would guess they are probably more expensive than a semi.
The last time I had one in my drive it caved in the asphalt a bit.
