I used to be a die-hard Miller guy, with the occasional Leinenkugel's for a "treat". Leinie's Berry Weiss is just awesome.
My buddy turned me on to Busch Light, and it's my new go-to beer. Only time I'll get a Miller Lite now is if the bar doesn't have Busch.
Here's a fun fact I was told by a local beer distributor: The reason some bars don't carry Busch Light is because Anheuser-Busch is worried that it would outsell Bud Light, and they can't have their "cheap stuff" outselling their flagship brand. In bars (at least around this area) that serve both, Busch is almost always the better seller.
