Here's what happens when your Tesla Roadster (or any EV) reaches the end of battery life

You should try Bison.
I tried some grass fed beef. It wasn't as tasty as the regular beef. And it was much more costly. And steers need grain to grow fast. I have a friend with a couple of cows and a couple of steers. Pasture fed during the summer along with a grain mixture. During the winter they eat baled hay and a grain mixture.
He has a tractor, a hay mower, a tedder, a baler, an elevator, etc. It's not cheap to grow cattle anymore.
