Hello bbpostcards, This looks like Bellingham ballpark, have you checked images for the Bellingham Gillnetters or Bellingham Chinooks? B-ham ballpark had houses right on top of it like this image, but I can't find a good image of the grandstand.... I can tell you it's not Electric Park in Aberdeen, any of the Tacoma Bowls, or any field in central Washington (Yakima, Wenatchee, Walla Walla, etc..) Best of luck and as always great stuff!
