The Chicago Adler Planetarium is having a free admission week this week! You should be able to find metered parking if you get there early (they open at 10AM), but there are also lots available. Chicago Public Schools just went back into session, so this might be a great time to go if you are home-schooling or have little ones still at home.
We’re already planning to go to the Field Museum on Friday, so we might just have to make a day of it and walk over here for awhile!
(Thanks Mummy Deals!)
