I actually prefer to have only a few contacts for pot and try to stay "under the radar" so to speak. My one or two guys get decent buds with a good price so I stay where I'm at for now.

On the otherhand, networking outside of the dealing scene is my specialty
I shake hands and exchange pleasentries everywhere I go and has yeilded me more friends that showed up at random times when needed or free dinners because somebody knew me, than anyone else I know. That kind of networking I can vouch for.
