I live in the foothills of Colorado and there are trees, rivers and lakes everywhere. Any tips on where to start looking or what pieces are worth retrieving or should be left be? How do I disinfect or clean them as parasites and weird things living in the wood are my biggest fear with collecting my own drift wood. Bottom line is whether I collect it or pay for it someone is finding it and prep'ing it so I might as well do the work myself and cut out the middle man.
