Western Michigan University's ice rink is open for public skating, weekend afternoons and at lunchtime most weekdays. Admission costs $3 ($1 on weekdays) and skate rentals are $1. Because it's indoors, it's open regardless of weather. The arena also offers broomball competitions and open hockey. It's home to WMU's hockey team. Lawson Arena website
