The MN Special Hockey web site has a calendar that you can subscribe to. That means you can view along with your own calendar on some phones (iPhone, Android) and with some calendar software (OS X iCal, Google Calendar, Outlook 2010).
Just use this Calendar address with the "add calendar" feature of your software:
webcal://www.mnspecialhockey.org/ical_feed?tags=196799The right side of this news page also shows an agenda view of official calendar. You can click on the icon (+Google Calendar) to add it to your Google Calendar view.
