seventeen cents

I owe a major update with pictures from the past 2 weekends. But until then, I had to comment on gas prices. Yesterday when I went to work, gas was 2.32 (pause for the jealousy of how cheap our gas is). But when I went home, it was 2.49. That's a big jump for one day! So my question is, was our gas just way too cheap and caught up a bit, or did gas go up about 15 cents for everyone??
