I am traveling to Israel for the first time this summer, and generally when I go to a country I like to learn a little bit of the language to make navigation easier (and because it's cool).
However, I'm already reasonably competent in Yiddish and would love an opportunity to actually use it (and really don't know Hebrew well at all). Is Yiddish spoken enough in Israel that it's likely to come up? Are there parts of Israel where there might be more Yiddish speakers?
