Families at Illinois’ Ski Snowstar Winter Sports Park rule on Sundays, when anyone under 21 gets a lift ticket for just $17 when a parent purchases a regular priced $34 ticket, saving you 50 percent. On Super Bowl Sunday, Feb. 2, come to Snowstar for “Souper Bowl Sunday,” when all tickets are just $20, or 41 percent off regular price, if you bring a canned soup donation for the local food pantry.
