How far is too far??

How far is to far? Today I have to go to this school that is about 45 miles away and while to most people that is about 45 minutes to me it is more like an hour and 15 minutes b/c of traffic and two lane roads. Now for the most part I enjoy what I'm doing, outside of the driving part and I'm slowly getting use to that but an hour and 15/20 minutes away. Come on now, I feel like I'm being taken advantage of. I have a hard time saying no cause well I still want them to call me but I think this school is going to be my first and last day there. I was told by "K"ay that this school is looking for a PE teacher on a full time basis and that it would be great for me but now that I look at the drive, is it really worth it? The other thing is that I'm only teaching 1 period of PE, but Kay said they were desperate for a specialist for this one lesson? Not sure why one of the other teachers couldn't cover it but well whatever. Anyways, this has gone far enough (sorry bad pun), no more school over an hour away.
