As of yesterday I've tried both the Pepsi and Mountain Dew "Throwbacks", and I gotta tell you, I was surprised. They taste better than the regular versions, oddly enough. If tasted cold, they're lighter and crisper, lacking that syrupy aftertaste quality that hangs around in your mouth for far too long. I'd drink it again.
In honor of Mountain Dew Throwback, dig this Chuck Norris Dew spot.
