I'd never pay for firewood, unless it was some kind of *'cut your own' deal. I was thinking this morning what I'd do though if offered a cord of oak or a cord of cherry, same price. I think I might go for the cherry. Oak has more heat, but I really like cherry.
*Last year or the year before I was on a job that got logged, and the slash left behind was unbelievable. I could have gotten it free, but I don't have the transportation or storage for something like that. I was thinking you could make some money on top of the logs by selling access to craigslisters. Might be more of a PITA than it's worth, but on that particular job, there was thousands $ of quality firewood left on the ground looking all shitty. Get it cleaned up, and get some money for it too.
