One of the best things we found on Mercer Island is access to this wonderful milk delivery service. Smith Brothers Farms brings us fresh dairy products every Thursday morning, for roughly the price we pay in the grocery store. The milk comes directly from the farm, (presumably that means happier-than-average cows ?) and in a blind taste test our kids preferred it to the store-bought stuff.
