Last i had Pliny the Elder, was at a small bar in downtown San Diego (I was there on vacation last August). It was very hard to find.
Pliney the Elder is available year round in a a few liquor stores in San Diego in pint bottles. A bit hard to find, but if you know what day it's delivered... Pliney the Younger is only released once a year to select pubs, and you have to wait in line to get a pint or two in the morning/early afternoon. Pretty much a one day thing down here.
