Remarks:

We had a hard time keeping gulls in the chum line. No gulls followed the boat out of harbor. We returned close to shore to pick up gulls at Navy Pier, which we brought with the boat to two miles off shore. But there the gulls abandoned the boat. After some time, we did pick up a following of two dozen or so Herring Gulls plus a couple of Ring-billed Gulls, and these attracted the jaegers.
