Theres a number of cases in baltimore involving different sets of the bloods street gang being connected to their respective west coast counterparts either through paying dues or drug trafficking. One of those cases involved a high ranking blood from LA that was collecting dues and selling heroin in baltimore ended up torturing and killing someone. I think any city where you have a large number of blood and crip sets your gonna have more than a few of them having west coast ties in some form or another.
