They had a clubhouse in Camden in the early 90s; back when that city was completely outta hand with the Sons of Malcolm X gang, etc.
The Philly area is def ruled by Pagans nowadays. You don't see a whole lot of Warlock Patches around much, don't know exactly why. Still a bunch in South Jersey. Wheels of Soul move somewhere in between. The Breed are typically outside of Philly and up in central Jersey.
You forgot the Wheels Of Soul MC in Philly ( 100 patch members). Black/Mixed 1% clubs are seemingly the most low profile in the biker world, since you can hardly find any in depth investigations on them.
