I know this is not exactly what you are after, but maybe contact local fire brigade, arborists and tree surgeons, in case there are any logs left from the trees that blew over in the last few storms. Or they may at least be able to tell you where those logs went. Maybe put a want ad in a local newspaper offering to remove logs etc, stressing that you will be using them for woodwork, not firewood. You won’t necessarily be able to use it straight away, and it may not be the right size for a particular project, but it will be good to practice on.
