I've totally noticed this too! When I was down in LA with the band in January, every single grocery store we went in was just crammed full of macro crap. Totally disappointing. According to ratebeer.com, there
are some stores with good brew selections, but it's nothing like the Pacific Northwest, where even the worst grocery store selections still yield plenty of drinkable choices!
I toured the Stone brewery in Escondido in January...really cool. The tour guide said that the amount of beer that Annheiser-Busch spills in a year at their breweries is over ten times the amount of beer that Stone brews in a year! I was thinking though- the lack of ingredients in an Annheiser-Busch brew makes those spills probably hardly any worse for the their bottom line than if they had just been spilling water

Notice the Behringer PA speakers
What they lack in pro audio knowledge, they make up for in their beer
