Their main areas varies and somewhat overlap. Chosen Few started in L.A so obviously California is on thier back but you also have WOS chapter in Cali. Outcast is Detroit and Sin City is Gary so they both in each other states most likely. WOS in Philly and yet have a large presence in the Midwest and parts of Northeast. Thunderguards have Delaware and surrounding Mid Atlantic area.
Down South it's a mix of the 3 or 4.

So far WOS are having a rivalry with Outcast & Sin City. Yes , smaller clubs that associate with them are support clubs.

If you think you are too small to make a difference, you haven't spend the night with a mosquito.
