That said, when I lived in Chicago, I used to see a lady who rollerbladed to the office. I am sure you're thinking, "Young techie, jeans & t-shirt", but you'd be wrong. 40's or late 30's, dressed like an exec. Wearing a dress, make-up, string of pearls, with a fancy handbag, nice haircut. I don't think this is a relevant data point (clearly an outlier), I just thought it was awesome and wanted to share.
