Why does the man want to visit New Mexico?

M: (1) I’ve been studying too much and need a change, so I just made plans to go away during the January break.
W: Really? Where are you going?
M: I’m planning to visit New Mexico.
W: Hey, my sister and I vacationed there last year. We had a great time.
M: Did you get into Albuquerque?
W: Sure, whenever we were skiing.
M: Is it far from the mountains?
W: Not at all. See, even though (2) Albuquerque’s on a high, flat plateau, there are even higher mountains near it. Just half an hour away from the city, there are snow-covered slopes.
M: Well, if the mountains are only thirty minutes away, I guess I should take my ice skates and my skis.
W: Definitely.
M: I heard that the weather there is great.
W: It is—low humidity, moderate temperatures. (3) But you do need to be careful of the high altitude.
M: What should I do about that?
W: Oh, just take it easy for a few days. Don’t go hiking up the mountains or exercise too vigorously. Just do everything gradually.
M: I’m sure I’ll be fine, and I’ll let you know all about my trip when I come back.
