No matter how many times I've seen it, I can't seem to get tired of the Museum of Science and Industry's weather exhibit. It's fun and interactive and there's wind tunnel! What more could you ask for. If you live in Chicago and have never been there or ever plan on stopping through, I highly recommend it. I have another couple free passes that expire in June and yes I do plan on going at least two more times before then. Plus, it sets up a really cool photo opportunity.
