Here, have a look at this. I hope you don't mind me having played around with your photo a bit, Joe, but I increased the contrast to +30 and attempted to pinpoint a few spots. My guess is that inside the black circles are indeed dust spots, albeit very faints ones for which a rejection should have been borderline, I think...
Edit: I totally understand what you mean, Joe, it's going a bit too far when you have to examine the photo this carefully to find spots. However I do think I located a couple of them and if you just clone them out, the photo should be good to reupload.
