Why does the woman know so much about Albuquerque?

M: I have been studying too much and need a change. So I’ve just made plans to go away during January break.
W: Really? Where are you going?
M: I’m planning to visit New Mexico.
W: (4)My sister and I vacationed there last year and we had a great time.
M: (4/5)Did you get into Albuquerque?
W: (4)Sure. We were skiing there.
M: Is it far from the mountains?
W: Not at all. You see, even though Albuquerque is on a high plateau, there are even higher mountains near it. Just half an hour away from the city there are snow-covered slopes.
M: Well. As the mountains are just 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. No humidity, moderate temperatures, (6)but you do need to be careful about the high altitude.
M: What should I do about that?
W: Oh, just take it easy for a few days. Don’t hiking the mountains or exercise too vigorously. Just do everything gradually.
M: I’m sure I will be fine. And I will let you know all about my trip when I come back.
