I see my folks virtually every day, I see my sister and her kids once a week, I run into aunts and uncles and such at least once a week, and I visit my grandmother -- well, that varies on the month. I usually try to see her at least a couple of times a month, but sometimes it's more if there are holidays and birthdays together.
Most of my paternal family lives in my same county, and many on the same county road. There's one oddball in Georgia.
As for my maternal family -- I see my aunts and saw my uncles maybe once a decade, the odd cousin once every five years or so. My mom's brothers moved to Texas and her sisters to California, but after the brothers died (both of lung cancer!) the cousins moved to California, too. The California people are technically my relations, but as I never see them I don't really think of them as 'family'. My aunts are just the women my mom argues with on the phone every other day.
I used to consider moving to Oregon, but with my niece and nephew growing up, and my grandparents getting on years, I decided against it. I'm glad, too, considering how rarely people seem to see their kin!
