I took the girls to the Wonderland Express - it's the wintertime model train that the Chicago Botanic Garden sets up. The girls oohed and ahhhed when we walked in. We were fortunate to be able to go when it wasn't busy.
The trains and the lighting, the plants and all the miniature buildings were amazing, but I think they liked the fake snow falling INSIDE the building the best. Claire is trying to catch some in her mouth below.
