CCI = DB + OB * temperature / rain

Weird title? Let me explain...

This morning was pretty chilly. In fact, it must have been quite freezing since when I left my house I noticed the frozen windshield on my car and some frozen puddles on the way to work. Despite that I counted 2 (!) other fellow cyclist on the road. Those of you living in more urban area such as Cambridge or downtown Boston will start laughing but seeing two other cyclists on a cold winter morning in Arlington is a lot. Most people drive here.

That weird equation in the title of this post is a way of describing this with numbers. Let's say that CCI is a City Cycling Index and it shows how many bikers are out there on the road. There is always a few, no matter if it's a pleasant sunny day or a center of the hurricane Sandy - they are Dedicated Bikers and they always ride their bikes. The number of other cyclists - the Occasional Bikers, strongly depends on weather. It is directly proportional to the air temperature and inversely proportional to precipitation. Well, in most cases.

In some cases it isn't. Such as in the city of Oulu in Finland. It is located pretty far north at the coast of The Gulf of Bothnia and locals enjoy temperatures of -30C (-22F) more often than we do. I am not kidding - they really seem to enjoy it. Otherwise how would you explain that there are more bikers out cycling in those freezing temperatures than we see here in the summer? See for yourself:
So the next time you think it is cold outside and you will want to drive instead, think about people in Finland.
