I don't understand how the cost of fuel would blow the "lid"off of cord wood prices. It has to me other aspects of the economy and the use of fuel therein that's killing the supply of cord wood.
Look, if a cord of wood cost 10 gallons of gas, lets say gas, that's a lot. at $4 per gallon the total cost of gas is $40, so add $40 to the cost of a cord of wood, don't add $100 or more and say it is because of the cost of gas.
I too have a lot of wood on my property, but I am limited mostly to white pine and red cedar. The hardwoods I have are so large I couldn't harvest without first hiring a tree service to take them down, even then they'd also have to "buck" the main trunk as that would take a 30"chain bar or longer, I estimate. Not sure what that would cost per cord, given I split, truck to the wood pile, and stack myself - I could also buck/cut the large branches myself, just not the main trunk. I, of course, really don't want to cut down those beautiful trees either. I guess if things get bad enough the I feel I have to take the big ones down, I'll need to stand armed watch to protect the wood pile.
