I just mentioned this in another post but (unfortunately) some ethnic vietnamese gangster types and their 'ladies' started moving into our neighbourhood and while that is definitely not a good thing because of the undesirables it attracted - its also true they did NOT want any sort of trouble from me or other foreigners in the neighbourhood. If anything they seem to go out of their way to be friendly and courteous. Which is fine. I'm not so much worried about them though again I sure don't enjoy some of their 'customers' who show up.
