Thanks, Marty for clarifying the location of "The Playpen" in Chicago. I was responding to a blogger who described as "Playpen" the area I referred to just north of Navy Pier, an area that is for commercial use and definitely not suitable or even legal for anchorage. As we both said, the North area of the Chicago harbor, north of the Water Dock , where the day anchorage "playpen" is located, is not a quiet anchorage, and has no dinghy dock or services. There is no suitable free anchorage in Chicago. The cheapest options are the Monroe mooring balls or the docks at 31st Harbor. -- Bob Kunath bobkunath@gmail.com 847-540-8175
