I think you'll be waiting a long time for national distribution of Yuengling!
I had some last week traveling though DC -- a big step up from the adjunct brews and not as "craft-y" (i.e. hoppy) as Sam's.
Not sure what the closest regional equivalent would be in CA. When I lived there some 20 years ago, probably Henry Weinhard's, but I recall it being only a minor step up from the Buds of the era.
Weinhards brings back memories of drinking beer with my grandpa when I was a little kid and then buying it by the case in college as an alternative to Bud/Miller/Coors and whatever swill was in the keg. I pick up a six pack every couple years to reminisce.
Good to hear there's Yuengling in DC. I'll be out their in April.
