Name for Hillsdale, a suburban neighborhood of Portland, Oregon, named as such because of it's large Jewish population. Businesses are closed every Saturday. All restaurants serve kosher food. The main secondary education institution, Woodrow Wilson High School, is practically a yeshiva. The Jewish Community Center is also located there.
I drove down to Jewsdale to get some kosher food and bagels.
My daughter goes to Wilson High in Jewsdale and she gets Rosh Hashana and Yom Kippur off since no one comes to school on those days.
During the bombing of the Gaza Strip, several Reedies marched through Jewsdale to protest since there's a lot of Israel supporters there.
