Speak with Fizzcrank Fullthrottle at Fizzcrank Airstrip.
Okay, I think I'm going to start making my way back to the airstrip, too. Of course, I'm moving a little slower with this leg injury.
Say, do you think you could get there ahead of me and pass on the good news to Ol' Fizzcrank? I bet anything that there'll be a reward in it for you.
