I can't wait for this!! Went for the first time last year and it was Mind Blowing. Henry Akins, also known as the Jiu-Jitsu Super Computer was dropping gems on us left and right. Also got to meet some rad human beings from all over the world!! Still a few spots left for any daring souls. Check out his site https://hiddenjiujitsu.com his shit is no joke!
P.S. Henry has a huge almost cult like following (does seminars all over the world) and I've invited him to come over to SteemIt. I think he will eventually. He'd murder it!
