If you are looking for a little family fun this month, you don't have to drive too far to enjoy it. 

The Field Museum in Chicago is letting all Illinois residents into the facility for free all this month. All you have to do is provide proof that you are an Illinois resident.

Normally, tickets start at $22 for adults and $15 for children 3-11 years old. Which means a family of four with two kids under 11 years old could save $77 if they went to the museum this month.

The free admission only includes general admission attractions, like the DNA Discovery Center and the Traveling The Pacific Exhibit. If you want to spend some money, but get the entire experience, then you can purchase the All-Access Pass, which includes a 3-D movie and some more exhibits including the Underground Adventure. For this month only, Adults pay $21, children 3-11 will be charged $15 and students and seniors will be charged $19.

Why do museums offer free admission? The General Assembly in Springfield has mandated by law that museums in Illinois have to offer up to 52 free museum days a year. Not only does Field offer free admission, but there are also other are Chicago museums that will have to do the same thing.

So if you and your family want to spend a weekend or maybe the day off for President's Day during the week, then head to Field Museum for free!
