Referring to your original question, "should we push for a park?", not at the expense of boater river access. I agree that the land needs to be secured. A play park upriver could provide great recreation for a small group of users, mostly locals. Tourists would likely go to Glenwood. Fishing and floating the Gold Medal waters of the Roaring Fork certainly brings tourist dollars.
River parks also have peak times and become unpopular at low flows. That could coincide nicely with fishing clear rivers. I don't believe the DOW is concerned about securing access for those who simply float.
