Re: I cant decide where to move for my music career
If it's christians you seek, then start looking in the most obvious place for them. Why not grab a phone and start ringing various churches in the three cities and checking out the scene that way. Ask for contacts who are playing in church bands and what not. Speak to them, get their take on the christian metal scene in their city. Surely someone will be able to give you a few leads.
I don't think asking "2 to 4 people" on Craigs List is enough 'market research' for you to be honest. Dig a little deeper before you decide. No point packing up and moving if you're not likely to meet the kind of people you want to play with.
