yes, you can get it from the lake (I live on lake onterio LOL) and plan on getting some this summer when i go fishing. What you do is boil it in a pot for a couple hours on simmer (low heat) that will season or cure it. It will kill any creepy crawlies , germs, fungus, and bacteria. Boiling it will leach out most or all of the tannins, keep boiling it till when you add more water in it is not tinted brown anymore. natural wood might not have any left anyway if you find some bleached white. If it wont sink when you are done you can go to the hardware store and get some screws that dont rust (galvinaized i think? they will know there) and go to home depot or lowes and see if you can find a piece of lanscape rock, about a inch thick and wide enough for the wood, ask them to drill a couple holes in it where the wood will attatch. voila. DIY 100 dollar driftwood centerpeice. I made mine, the one in the center with the curved wood peices, that is actually three peices each one screwed into the base and one screwed into the other piece of wood. easy since i asked the hardware place to drill the rock for me, did it for free. i had them drill one on each corner and one in the center so i had more area to choose from on the base.
