The two, along with three friends, had constructed a 91-by-43-foot rink in the backyard of one of their homes in December so they and others would have a place to skate.
"I understand what your purpose was; the problem was how you went about it," Cook County Judge Daniel Lawrence Peters said at the Bridgeview courthouse. "If you have contacts with the Park District, you may be able to do something with the rink."
Their time on the ice could count toward their required hours if Nelin and Ryan can arrange to host a skating program for kids through their local park district, Peters said.
