Welcome to the wild and wiley Morgan world. There is a big US presence, in case you didn't know. The Texas Clubs are a good start, they will put you in touch with the Morgan owners in the state, and they do have good fun. Texas is sort of in between the other big clubs, e.g. Southern California and MOGSouth (Southeastern USA). Either might be worth joining as well. I don't know about So Cal, but MOGSouth does has a member in Houston with an M3W.
Cheers,
