Gas is 1.89 in my area, what are the ripple effects of this era of cheap gas in America?

It's down to 2.20-2.80 where i'm at right now which is surprisingly low seeing as we're used to the mid three dollar ranges. This has been going on for about a week already which is pretty fast as we only have those prices for about a day, but I never put much importance to it until now.
