Over the summer, many Chicago Museums let Illinois residents in for free, and this fall one specific museum is continuing the freebie fun.

According to TimeOut Chicago, The Museum of Science and Industry is offering free days for Illinois Residents throughout the month of September.

Every single weekday in September ( 6–9, 12–16, 19–23 and 26–30) is free for Illinois residents, how cool is that!

This is the perfect excuse to plan a fun day with your kids for next to nothing. More information is available here.

If you're not free in September or you'd like to go to a different museum for free, there are also free days throughout the rest of the year.
