I am a busy mom who loves to get out whenever I can on easy SUP runs. My days of serious whitewater are over... now I just want to get out to enjoy the water without stressing since I wasn't that great of a kayaker anyway. Lakes are fine, but looking for mellow runs. Northstar Preserve near Aspen is great (and that is super mellow...) when nobody is there. Grizzly is great too. Other suggestions?
