Down in Fairfield and New Haven counties, it's showing up on tap now. So I think you have a good shot!
With respect to growlers, many bars do them, but there are a few problems:
1) Bars charge the per-pint price (which for a beer like SoS is often $8 or more) so you end up paying big bucks
2) Bars are not particularly good at filling growlers. No CO2 purge, lots of foam, etc.
I buy growlers from breweries only-- never bars, in CT. Retailers do not do growlers here.
