Kosher in Washinton
Do you mean Washington State? From a map, and from the little I know of the area, Portland is the nearest community of any size likely to have kosher food shops. That said, in the US at least, I find that I only need a kosher shop for meat, cheese, and random little specialty items such as balsamic vinegar. I don't use too much in the way of prepared foods, and as such, I don't often find that I need to head to a store specializing in kosher food.
