What had the woman been trying to do earlier?

W: Hello.
M: Hi there Susan. This is Tom.
W: Oh. Tom! Where have you been? I called you a few times. I even stopped by your place, but you weren’t there.
M: Sorry, I didn’t tell you. We go to Indian Lake every Fourth of July. It’s kind of a family tradition.
W: Indian Lake? Where’s that?
M: Uh, it’s about an hour and a half from Chicago. My parents have a cabin here.
W: So, it’s just you and your folks there?
M: Yeah, but they have to go back home tomorrow night. Say, would you like to come out?
W: I’d love to, but I can only stay for the weekend. I have a test Monday afternoon.
M: I can get you back in time if we leave early Monday morning. You know how the drive is on Monday morning!
W: You don’t have to drive me anywhere. My friend just sold me her car; that’s what I wanted to tell you. Now... how do I get to Indian Lake?
