Where are they going?

W: Will you be going to the conference center today?
M: Yes, I am thinking about it. What about you? Are you going?
W: Well, that depends on whether I can get a ride with someone here. I didn’t bring my car to work today because my husband took it to Montreal on his business trip. He said his van uses too much gas. Anyway, I would have driven his van to work, but I am not used to driving such a big thing.
M: Hmm... if that’s the case, why don’t we go together? My car is parked in the back. I’ll go and get it and meet you at the front parking lot in five minutes.
