One sister lives about 30 minutes away--I see her & her family about once a week!
My 2 brothers live in the Richmond, Va area. My older brother comes to NY for Christmas, my younger brother comes for family events. But I see them a few times a year, because my 2 sisters live in Northern VA, and we go there for birthdays & we switch holidays (this year, Easter & Christmas in Northern VA, Thanksgiving in NY). My sisters come to NY every other month, but it's easier for them--one sister isn't married, the other has 3 kids all under the age of 10, so they don't have tons of activities.
We do make an effort to see each other thru the year--in fact, we're going to VA at the end of the month for my niece's birthday, they were here in June & August for other family birthdays.
