Yuengling made a huge push here in Massachusetts, but after bumping craft beers out of taps at many local bars, it hasn't been able to sustain the initial momentum. I think people realized that once it wasn't the "new big thing," it just wasn't all that interesting.
I was on a big Fat Tire kick for a while, but after getting a case of it brought back for me earlier this year, I'm not as big on it. Still good, but I'm not ga ga about it any more.
The only beer I physically wasn't able to finish was a Samuel Adams Double Bock. Maybe I just got a bad batch, but I remember bringing the last of the 6-pack to a Pats game so I wouldn't be upset if I had to throw it out before crossing Route 1.
I would consider myself a "fringe" beer snob. I have friends who are way over the top about it, and if they bring back something interesting, I definitely can appreciate it. But I won't drive hundreds of miles just to sample the latest session beer or whatever.
