According to Us

1: Tribe is family; it is thicker than any bloodline you know of and stronger than any emotion ever felt. It knows who you are and what you stand for. Constructed of people that share the same common passion and love for a sport but have a greater understanding that it is more than that; it is a lifestyle that is not easily controlled but yet it is a life that totally consumes who you are.   

2: A group who believes you are only going to get out of it what you put into it. Facing failure is the only way you will truly ever succeed and taking hand outs is a form of entitlement. You will not see Tribe members walking around with silver spoons in their mouth but stitches over their scars.

3: A person possessing the strength & courage to stare straight into the soul of a Buffalo to find the answers; also: one who is willing to stand and fight for the beliefs in which are instilled in them.
