Thanks! The info definitely points to bitter pit. I will follow the instructions here. Question: I spoke with one of the orchardists in Hood River, he mentioned adding lime. I noticed that some of the orchards were spreading lime. I suppose I should check soil pH first.

Yes, the first of several things. Thinning at the appropriate time will help as well.
