@ehBeth,
Oh, home is a malleable word.
My home is Venice. I have walked the whole area over and over and over and up to Santa Monica and through the Marina which is to the south from 1974 to 1999 and beyond, thousands of walks or jogs. Our house (perhaps I've photos of the remod by others, plus with the new scanner I can scan old photos..) there was the heart place. My ex told me the house just sold again (#3 including my sale) a few months ago, my baby house. Trust me, I don't want to know for how much money. It was a simple 'teens beach cottage, california bungalow circa 1913 (various ages turned up over time).
I'm still comfortable walking Venice, still know neighbors, besides knowing the streets and homes. This will change, natch.
But - I have homelike feelings about many places, varying with time and attachment.
I feel a strong connection to Rome in my heart and mind, weird as that is given my advanced antipathy to my former religion. I think Rome stands for all the travel I never did, all the sights I could have gone to and learned to see, all the people who have, through history, been through so much.
Albuquerque is also home, that is, this is most immediate. The breadth of home-ness is cut short by my personal access changes, so I don't whip about town as I would have not all that long ago. People are pretty friendly, I'm feeling more comfortable as a non southwesterner (I've gathered southern california is some island place that doesn't count for being west or south), and I have dear pals here.
Further on a limb, I'll say home is where I am, given a bit of time, usually - it has to do with me.
