Thing I have heard people do in this situation: 1. Change location in LinkedIn to new city. 2. Get in touch with relevant employees at companies in target area, e.g. another data scientist. Ask if you can do quick talk about their company and what it's like there. You get to learn more about company that way. Sometimes you can hear about jobs that aren't posted, or they'll want to submit your CV because of referral bonuses, etc..
