CHICAGO (CBS)–Metra is offering free rides to passengers this weekend on all service lines as a way to “boost weekend ridership” and give passengers a “pat on the back for coping with last week’s extreme cold,” Metra said in a press release.

The offer is good on Feb. 16 and 17 only, but Metra is implementing its “Family Fares” special on Monday, Feb. 18, when many schools will be out for Presidents Day.

“Family Fares” allow up to three kids under 12-years-old to ride free with an adult.

“We survived the polar vortex – now let’s have some fun,” said Metra CEO/Executive Director Jim Derwinski in a press release. “There is a lot to do in Chicago and the suburbs and Metra can take you there. We’re hoping this weekend will convince people who have never ridden Metra or who haven’t ridden Metra in a while to become paid customers in the future.”
