For what reason do people rollerblade at 3-4AM?

This is really interesting!

I'd like to see ice skating and ski/snowboard separated into two categories, since the former is often done indoors whilst the other two rely on the short period of daylight there is in the winter

From this chart it's pretty clear which hobbies are holiday hobbies (broad bellcurve around midday), which ones are after-school (sharp bell in the evening), and which are for commuting (double peaks or none at all).
