I hear ya and a lot aren't there's very few I trust on here but have been chatting with them for a while...I'm enjoying watching the fruit of your labors!
Now that I think about it, a deer was hit outside my work this past summer. My boss dragged it out back. That was a while ago prob all decomposed now? Maybe find the bone's and get a couple cups full? It was close to the shop so nothing really got to it. Gona check this out next summer. Too much snow now lol.
