Wagonhammer seems overrated to us. We spent a few nights there last summer. They were pleasant enough to us, and even held the shadiest spot for us. I think they are fine if you don't mind sites close together with no shade, enjoy their "happy hour" with other campers (no real amenities, just a gathering in the evening), and especially if you are regulars. We probably won't go back. Not a lot of good choices in/around Salmon, IMO. Sorry to hear about the "no pets" at Heald's Haven - we had thought of using them if we return, but can't with that stipulation.
