C7 (crew)

Originaly Founded in Florida, the C7 crew has become a large social group protecting anyone who is a part of it. It is now branching out to the UK and is making roots in london and the south east. It gained its name through many scources, but mainly because it was formed in the year 2007. Other reasons would be that at the time that the crew was given its name there were the 4 founding members and 3 newcomers and the 4 founding members lived in a place called 7 oaks. however one of the founding members moved out of florida to the UK where C7 became international.

If your against one member of C7 (crew), your against them all.
