Where is home?

I saw this on Iranian.com today:
"WRITING CONTEST
New California Media (NCM), in collaboration with the California Council for the Humanities, is launching a contest to "Write a Letter Home" to a real or imagined relative about their life in California. The twelve best letters received statewide will win a $1000 cash prize each. Please send your "letters" to iranian.com [times@iranian.com]and we will forward to NCM. The winner will receive the full amount of the award. NCM will have them judged by a distinguished panel. The deadline is January 15."

This sounds like a good opportunity for getting paid to write creatively. I look forward to reading the $1000 letter. I wonder, however, what the organizers have in mind when they say "home." What to do with multiple homes?
