Yes, some Russian stores have it, but there are none in my neighborhood. Polish supermarket has one good variety but sold as whole herrings, so I need to gut and clean it, which nobody in my family likes. I meant it's not easy to find, but possible of course. Easy if you live in a Russian neighborhood, but I try to keep as far from those as possible. I prefer to selectively enjoy elements of Russian culture I like, without the multiple things that I dislike.

I like neighbors that smile and say "hi!" :-) I think a "fake American smile" is so much better than honest Russian rudeness. I'm prepared to sacrifice frequent herring consumption for not living in a gloomy Russian community... I will probably get some angry comments for this, but it's a free country :-) Many like living in a Russian neighborhood, so everyone chooses what he likes, nobody's forcing people where to live. So this is a strictly "IMHO" kind of comment...
