Apparently the second block 5 booster is on the test stand in Texas.

There's not really anything new or surprising in the article, but it points out a kind of cool possibility: This booster is likely going to the west coast, where they only launch once every couple of months. In theory, it needs no refurbishment between launches. That means that this may be the ONLY booster to launch off of the west coast for the next couple of years. Would be crazy if that works out.
