I will be the voice of lack of reason: Go get the pump at day break if it means a lot to you. If you can see a far distance to where the cars are coming from and don't mind a sprint.

However, this is coming from the girl who jumped the subway tracks, went home with a stranger because she was trapped in Berlin (who gets trapped in Berlin), spent multple nights in airports and train stations, and lived to tell the tale but not to her parents.

now that you know what kind of person I am you may want to listen to the others.
