Russian River isn't distributed here so you won't be able to find the Pliny. Redstone Liquors in Stoneham had the Ballast Point Big Eye IPA, not sure if they still have any now but it's worth a visit because it's a great store.
Yeah Sculpin should def be available but its verging on being a few months old at this point unless its the 12 ounce bottles. The hop characters on this one dont hold up real well unrefrigerated so buyer beware. As far as Russian River goes you may be SOL, but with that said there area a handful of bars in Philly that have Pliny on tap almost all the time. SOOO maybe Boston is the same
