I just saw the update from Whip In showing these have hit Denton County. I've been looking forward to trying the Obsidian, I don't think I've ever seen it in Texas
I had Obsidian on nitro in Denton at oak street drafthouse. This was a week or so ago so they may not have it, but regaurdless, thats a great place and worth checking out if you haven't already.
Houston has had Obsidian for a few years, it recently launched in DFW and Austin about a month ago. Will be spreading around the state soon. The Stoic going around is another wave of the 2011 Stoic, more was recently sent down from the brewery, but will be limited to DFW.
