Sam Adam's ain't cheap - thats probably why, lol. I had a few of my friends try to indoctrinate me with how superior Corona was, and I just can't stand it. If I want a beer that will kill my appetite for a 2nd, I'll drink a Corona.
I've heard GOOD things about Landshark - And it's funny you mention that.. I'm actually wearing a 'Landshark' shirt right now. For your enjoyment.
