It doesn't sound like it's worth it to me... that is a crazy drive no matter how much you love the job. For $10/hour, I think MMM would say it is ridiculous, particularly if your shifts are short.
Are there other options? Can you volunteer doing something similar that is closer to home (hard to say without knowing the work involved), can you work from home doing this type of work?
Personally, I would look for a similar opportunity closer to home. Perhaps talk to the new employer and see if they can do something to help you out somehow? Maybe they have a connection/office closer to you?
Good luck! Sorry for my totally blunt opinion. :)
