W: Hey, I heard you are just back from a trip. No wonder you look so healthy and spirited.
M: Nice to see you here. You are right. I did enjoy it a lot.
W: You like taking trips, don’t you?
M:(6)Absolutely, that’s the best way to relax myself.
W: Tell me something about road trips! I bet you know a lot about it!
M:(7)Yeah. Ah, me and my friends, when we were in high school we took a lot of road trips to lots of different places.
W: OK.
M: We would go down to California, ah, sometimes Mexico. One time when I was living in Wyoming, at one weekend we drove from Wyoming, through Colorado, New Mexico, and Mexico and back at the same weekend.
W: Wow! Well, actually for people who are not familiar with the United States, how far is that?
M: It’s a long way. I don’t know. It took probably about 15 hours one way.
W: Wow!
M:(8)So, thirty hours all together. But it was fun. We drove down to Mexico, and had a good night, a good meal, a little bit of drinks and drove back the next day.
W: So you went to Tijuana?
M: No, we went to, ah, Ciudad Juarez.
W: OK. Nice.
M: That was really fun and a lot of other trips we took, ah, when I lived in Oregon, when we’d go down to California, and we’d surf.
W: Oh, really?
M: Yeah!
W: Oh, you’re a surfer?
M: A little bit, a little bit of surfer.
W: OK. What kind of car do you drive? What do you use for this road trip?
M: Well, typical American. Uh, a four-wheel drive vehicle, big vehicle... Lots of gas but a lot of fun.
W: Oh man, you’re from Oregon: you’re supposed to be a tree hugger!
M: Yeah. But there’re good things. One rule we had on our road trips was that when we saw any lake or big body of water we had to stop and swim in. It was a good thing to do.
W: Well, you live in Japan now. Do you ever take road trips in Japan?
M: I took a road trip from Niigata up around Hokkaido and back, so it was a long road trip actually.
W: Wow! What’s the difference between a road trip in Japan and a road trip in America?
M: Well, a road trip in Japan... It’s a little bit more difficult to get around. It’s a little bit more expensive. Uh, in America road tripping is sort of something a lot of people do.
W: Yeah!
M: And in Japan, when we do that it is a little bit strange, a little bit different, and not very normal.
W: Yeah, that’s true. OK, great. Thanks a lot, Steve.
M: Alright.
