As I mentioned when we visited the Brick Safari at Brookfield Zoo, the nearby Morton Arboretum happens to have a Lego exhibit this summer as well. Whereas the Lego animals at the zoo were all life-sized, most of the ones at the Arboretum are far larger than their living counterparts. Our first Lego encounter was with a bee composed of 16,383 Lego bricks, which took 200 hours to build; our last was the Monarch butterfly, with almost 40,000 bricks and 425 build hours. Imagine spending all the time assembling Lego. And getting paid to do it! 
The Arboretum’s Lego exhibit includes fifteen displays, all within walking distance of the Visitor Center; if that’s all you see, you’ll walk about a mile. We walked a bit more than that, exploring the Children’s Garden as well. We visited on a rainy Sunday morning, so there weren’t a lot of people out and about; I think we only saw two other families in the Children’s Garden.
The sun emerged as we meandered through the Hedge Maze, vaguely looking for the promised nooks and crannies that harbored information on specific plants. As we finished off our Lego hunt, walking around a nearby lake, we emerged by the parking lot and a rock-bearing troll from the Arboretum’s Troll Hunt. We’ve seen the troll that’s visible from westbound I-88, but hadn’t managed to visit to see the other five trolls crafted from reclaimed wood that have been visiting for over a year now. We’ll have to go back to find the other four at some point.
