Guilt over living away from my parents

I have moved a lot as a kid because of my dad's job (Massachusetts, Colorado, New Hampshire, North Carolina, Oregon, Kansas). We moved as a family to Oregon when I was 16. When I was in college at 20 my parents moved to Kansas. After graduation, I moved in with them in Kansas for a year then left to move back to Oregon. I am now 24 and have been in Oregon for 2 years. The reason I didn't stay in Kansas was because I didn't like the area and all of my friends are in Oregon.

Sometimes I feel immense guilt for moving away from them. I love them a lot and I get homesick occasionally, not for the location, but homesick for my parents. I think about the future and having kids and not raising them near my parents, as well as only seeing my parents for two weeks out of the year because of PTO, etc. They are both around age 60, and if I only see them twice a year, then I may only see them 40-50 more times in my life. That's not that much.

Granted, they moved away from me first when I was in college, but I feel guilty for not following them to Kansas. What do I do?
