Grandparents?

If you have any, do you keep in touch with them? My grandpas from both sides died when I was like 1, and my grandma from my mom's side died when I was 10. My only living grandparent is my grandma on my dad's side. She is very intelligient. With an English background, she actually received a degree and teaches a weekly American and British Literature Class. And at 76, that's pretty phenomenal. I send her emails once a week to let her know how I'm doing in college, and she lets me know how her apartment complex is going (administration clerk) and how my twin uncles are doing. Get this, she had twins on her birthday. Hah! I feel she spoils and favors me most out of my brothers since we're the oldest grandsons by at least 15 years. Out of the blue this month she sent me a nice green fleece, and said she might send a penny my way soon. I'm surprised, because the way it sounds, she seems to be struggling with funds. I hope to go visit her soon. It's too bad airfare from here to California is a mess, but I'm sure I'll work it out. Do you guys have good relationships with your grandparents? Do you communicate with them often? Do tell!
