I dunno... When we get down around 100/dine, it seems like it's time for a time-out. Beyond keeping an account alive, I wonder what I'm doing worrying beyond that. I know there are True Believers here, and it will continue to alter your behavior. But that's 250 dines to a free trip (and not so much, on DL, anymore). Seriously, I just asked myself, "What am I thinking?!" (Actually, in truth, I got talking about this over dinner, and a friend said, "What are you thinking?!" To which I answered, "Oh...")
