Those 50 stickers could be depleted fairly quickly if your next job has an extensive amount of domestic travel. And by the time you hit Ma and Pa Keetle season next summer you may find yourself again back in the bus stuck between the Clampett klan going to see the Ziffels in Hootersville. (That's assuming the souring economy does not take away Jed's job at the factory).
I say take the trip and get to EXP. If not, you may be kicking yourself six to nine months from now.
