Hi, Thanks for your explantion. I indeed need some help to identify the zones. I have tried to do as described somewhere on this board. Checked one by one what the highest star rating is of each zone. However in L.A I don't find any with only 1 or 2 stars. I see following zones: Downtown, Aiport, West Hollywood, Hollywood, Marina Del Rey, Manhattan, Beaches, Burbank-Glendale or can I use also the one of other cities? Thanks for your help!
