Well, it sounds like a personal decision to me. Is the -$5 an hour+ worth the experience / travel? I can relate to wanting a change, this is often times a good thing.
I haven't told many people this, but I am going to join the marines after I graduate college (in a year and a few months). This is due to many reasons, most of which I won't go into here. But is part of it simply wanting a change? Sure. Change is often times a good thing, if it is done for the right reasons.
