"I have traveled to the west coast and southern California a few times with my family to visit cousins and loved visiting the area. I would not have any concerns about living here for five years to train with your amazing program. I look forward to soaking in the sun, playing nine holes on the weekends, and even learning to surf for some adventure."

If you have lived or visited the city or adjacent cities, you should mention this. If you know anyone there, talk about the good things they have told you. If it is an unfamiliar city/region, pick traits unique to the city that intrigue you and explain why an applicant may be open to living in the area. Make your interviewers understand that you have done your homework on the city/region and can see yourself thriving there.
