This is way more than usual. Gas topped out at $3.99/gal in July and now it's $1.75, so that's less than half of what it was before. I don't remember how much it went down last winter, but it wasn't that much. Also, I had an economics professor a couple years ago who said that regular gas will never go below $2 a gallon again. So that goes to show how significant this is. But yeah, it is really nice being able to fill up my tank for under $20 again.
