Your kids are off of school this Monday, why not take advantage of what's going on at the Adler Planetarium in Chicago.

Heading to the city can be expensive, especially when you're trying to take your kids somewhere fun and educational. Museums are pricey!

But thankfully, most of the museums in Chicago have a few free days sprinkled across the calendar.

This Monday, Columbus Day, is one of those days at the Adler Planetarium.

I'm bummed, I would totally go if I was off of work!

The museum fee is free for Illinois residents this Columbus Day (October 10), and also November 11 (Veterans Day), and December 3-9.

What do you get for free?

The Adler Planetarium website says the following:

Countless galaxies, unfathomable distances, exploding stars, diamond planets, black holes, there’s no way around it, space is freaking awesome! Come learn more at the Adler Planetarium during our Illinois Resident Discount Days – where Illinois residents receive free General Admission to the museum. Whether you are looking for free activities for kids, want to learn more about space or take in the amazing view of the Chicago skyline, free days are a great time to stop by! Please see the list below for more information on upcoming free museum days at the Adler and at other Chicago cultural institutions."

So get going!
