Spokesperson Ann Wasser -- also the director of Severson Dells Nature Center -- said they are offering a bingo-based challenge throughout all of January and February and it's called the 815 Outside Winter Challenge.
The premise is to explore nature in new ways and they've designed a bingo card to help you track your activities. The card isn't filled with rows of numbers. Each square contains a winter activity like "cook a meal over a fire" or "find a natural icicle."
Every time you complete an activity, simply mark off the square. You don't necessarily have to yell "Bingo!" every time you fill up a row -- or a whole card -- but you can enter yourself in a drawing for a gift card from local stores.
