I live within 15 minutes of the brewery and I have to say that I have never had a beer of theirs that I liked, other than their IPL. It's tough to change the local mentality that there is better beer out there than Yuengling lager, but I'm working on it.
Just speaking for me, I'm not under any illusion that Yuengling is a world class beer necessarily. I just like a good, affordable/cheap beer to keep around that's (at least in my mind) superior to BMC. In the days of $16 6-packs of Sculpin (not remotely worth that that price point IMO) among others, it fits the bill for me.
