I have noticed tree service guys have no idea of cutting wood to a desired length. More of cut the wood where they don't have to lift the saw.
There's no traffic in Mexico, NY.I took a peek at it, but I bought a dump truck earlier this year and I'm out of money. Come on over! I bet you could use a break from the Northeast traffic.
And for those of us that do both, I make sure to cut for firewood as I'm going, but I wouldn't expect a non-firewooding arborist to do so.
If I ran a tree service, I'd do firewood, mulch, milling, and maybe even kiln drying of my milled lumber. I always hate to see wasted stuff, and trees are so darn useful in so many ways.
