Yesterday, we were lucky enough to have my grandparents close to us, close enough that we could help them through a little bit of the heavier city traffic and bring them to our house. We got to take a 4 generation photo (Great-Grandma, Grandma, Dad, and Brooklynn). Yes, I'm outnumbered by females, but you work with what you have.
In a few months, we should be able to see the last two great-grandparents that we haven't visited with yet. We've been very lucky to have many family members make the trip to see us and Brooklynn; it's amazing how people travel for a new baby.
