Locate stores that have a keg of Russian River Pliny the Elder in SF area

Note: You don't actually have to buy the keg -- just find a store that has it...

I am looking for a keg of Pliny the Elder in 1/6th (5 gallon) or 1/4th barrel size. (Note: this is not the full keg size that you probably had in college...)

Basically, I am hoping that whoever does this task can call some higher end beer stores (or Russian River Brewing directly to locate a store -- http://www.russianriverbrewing.com/pages/contact.html)...and then provide me with:

a) store name
b) price for keg
c) cost for keg deposit at said store
