Actually, the existence of Busch Light means that anybody, anywhere can talk smack about low-end American "beers". If Budweiser is Clydesdale piss, Busch Light is watered-down Clydesdale piss.
And Busch Light is STILL better then Natty or PBR.
Both are better then Corona. Which frankly needs to be prosecuted by a world court.
If you like motherfucking BEER, and want a larger brand for some odd reason you should try these for pure, awesome 'Murrica:
Laughing Lab
Sam Adams (Any, but particularly Boston Lager)
Alaskan (any, but their red is a stand out)
Fat Tire
For my top 'Murrica micro brews or rarer selections:
Victory Golden Monkey - Belgian Tripel, your body isn't ready
Moose Drool Brown Ale
Arrogant Bastard (Any variant, yes it was named for me)
Dead Guy Ale
Kilt Lifter - Your body isn't ready. Get some woad, a kilt, and hang on.
