I'm wondering why using fresh (non-dried) wood is such a big taboo... I'd figure bacteria/fungus/parasite-wise, the dead wood people typically use is a higher risk, because once it's dead it's basically a free-for-all, contaminant wise. Is sap so dangerous? Supposing I cut some branches off one of my [dormant, since it's winter here] oak trees, water blasted them and baked them in the oven for a day, wouldn't that be just as safe as something that'd been dead for a few years?
