Fans of the CBS crime procedural “NCIS” know Brian Dietzen as Dr. Jimmy Palmer. An avid fan of road trips, Dietzen says, “When we were growing up, my dad and mom wanted us to explore the United States. Our family went to Yellowstone and all these different national parks. We went out to California every now and again, and we returned to the Midwest to visit with our cousins. Those trips were so much fun for us.” The Los Angeles-based actor is currently finishing up a documentary about the Wounded Warrior Amputee Softball Team, which pairs children with veteran athletes who share the same injuries.

An edited version of our conversation follows.

Q: Do you remember moving when you were a child?

A: Yes. My dad grew up in the Midwest and went to the University of Chicago for a while. We had a lot of relatives in the Chicago area. I have a bunch of family that still lives there. When I was about 8, my dad moved us out to Colorado. I was sad to leave, but Colorado is great, too, especially for the outdoor life. He wanted us kids to be raised somewhere that on weekends we could go hiking or skiing and stay active. I remember we didn’t have a baseball team at the time so we continued to watch the Chicago Cubs on WGN. Once we got the Colorado Rockies, I couldn’t change teams, so I remained a Cubs fan. I’ve been gradually moving westward and am in Los Angeles now. I joke that maybe I’ll retire in Hawaii or Japan. (Laughs)

Q: Have you been to Hawaii or Japan?

A: We went to Hawaii for our honeymoon. We also went for a family trip with my parents and brother and his family. I’ve never been to Japan. I’m not much of an international traveler. It has only been within the last three years that I’ve been to Europe.

Q: What kind of trips do you take with your own family now?

A: My wife and I take our children, who are 8 and 10, to visit national parks. We really enjoy that. My favorite trip that I’ve ever taken was this past summer. We rented an RV and took a monthlong trip, which was amazing. The kids slept so well. We got a bunch of books on tape and listened to Harry Potter on the road. We visited Yellowstone, the Grand Teton, Rocky Mountain National Park, visited family in Colorado and took our time going through Utah before heading back to L.A. We got to play it by ear. If we went to a place where we thought we might spend four nights and it didn’t turn out to be that great, we could pick up and drive to a different place.

Q: Do you tent camp a lot too?

A: Yes, we’ve done a lot of that and really enjoy it. But there were a few times when we pulled up in our RV and it was raining hard. And I was thinking how glad I was that we don’t have to play with poles and set up a tarp and try to stay dry. It was nice being able to just fall asleep after having cooked a nice dinner inside the RV.

Q: What is on your travel bucket list?

A: I’ve been to Canada and Mexico. I went to Monte Carlo and South Africa two years ago, but I would love to travel internationally a little bit more. I would love to go to Scotland and golf at St. Andrews. My daughter is a big fan of mythology and Greek everything. I studied Greek history in college. We would love to go to the Greek islands and visit some of the ruins.
