Need friendship advice. Am I blowing this out of proportion?

Friend advice, I guess.
Theres a concert on the 17th that I really want to go to. I bought two tickets in advance in case they sold out. Keep in mind, they were only like $20. But still..
The “friend” I solicited to go with me said she would. But she lives about two hours away (1 and a half the way she drives). The town the concert is in is 15 minutes away from me.. and shes wanting me to meet her half way..on the other side of town… and then drive her to the concert. (And then back to her car, 30 minutes away)
I’m not even asking her to pay for her ticket.

Is it ridiculous that I’m getting a little mad about this? I don’t really see the point in both of us driving back and forth like that.
I feel kind of rotten for being a bitch about this… but it doesn’t seem too fair.

Whats your opinion? And if you don’t think its fair.. how would you approach the friend about this situation?
**Also, should I mention she knows the city better than I do. So getting to the concert isn’t a problem, or finding the way there.
