My 7-year-old niece recently spent the week us “in the big city” as a mini-vacation and a chance for us all to spend more time together since we’re only able to see her family a few times a year. I asked her what she wanted to do while she was in the Chicago and her answer was “go to a park and ride a train.”  I’m not going to lie – the urban planning geek inside of me was a little proud that the two things that she mentioned were open space and public transportation.  But, in order to fulfill her wishes, I happily promised that we’d make sure that we crossed both of those items off of the list that week.
