Pictured Rocks is a very heavily used park, that is popular for trout fishing, canoeing, deer hunting, picnicking and hiking. Be nice to people you meet, and clean up after yourself. The
Jones County Parks people have been accommodating to us, so be a good citizen in return.
In Iowa, we don't drape ropes off of everything that we want to climb, as the scene is not crowded, and you rarely have to wait.
If you are going to top rope a route several times, and it is equipped with sport shuts, hang your own draws to minimize wear and tear on the hardware.
Finally, stay on the established trails, don't do things that will kill trees like wrapping webbing on them that will damage the bark. The rangers don't want you slacklining.
