Kewaunee County closed snowmobile trails Sunday morning. Some private clubs, like the Moonriders, hoped to preserve trails for riding. They said Saturday in a post on Facebook that conditions were “awesome” and, “We feel we have a very good base with enough snow to handle a couple warm days.” By Saturday night, though, even the Moonriders were throwing in the towel, closing trails at 8 AM. As snowmobilers are pushed onto fewer and fewer routes, etiquette becomes important. Owner Jeff May of May’s Sport Center has some tips.
