We went to the ICA on Saturday for a "Family Play Date." On the last Saturday of every month, admission is free for families, and they have activities set up around the museum for the kids to do. We started off with lunch at the cafe (because any outing is really about the food) and then moved on to sketching the waterfront.
There was an improv performance that involved the kids and some other activities we didn't make it to this time, but we'll be back! It's a beautiful setting and a part of the city we don't get to much.
