It now comes as no shock to learn that Mark, who retired from the Army, is at the helm of his own leadership development / inspiration outfit. The Tribus clan picked a nice warm climate from whence to base this endeavor, which goes to prove how smart they all are.
Today is Mark's birthday. I won't send cake - he might think it too caloric - but I'll post this vid from one of his bootcamps. Watch what happens towards the middle of the session. Oh, yeah... Go Army! Beat Navy! I mean... You can do it, everyone!
