The first day of Spring on Tuesday will be a little cold outside in Cedar Rapids, but a delicious treat awaits you inside at your local participating DQ.

Find your nearest Dairy Queen here.

On March 20, stop in to your favorite DQ, make a small free-will donation to the Children's Miracle Network, and you can get a free, small, soft-serve vanilla ice cream cone.

Last year, around $30,000 was raised through the promotion.
