I actually found mine while out hiking in our local dry river bed. There's all kinds of drift wood there. I find suitable sized stuff, take it home and wash it thoroughly in hot water and soap, and then microwave it for a couple of minutes. The water in the wood from washing it keeps it from burning. After it cools, I put it in the viv. They work great. Here's what the branches looks like in my amel and Okeetee's vivs.
