Is Beer Floating becoming a Finnish tradition?

This year Kaljakellunta is being organised in six different cities in Finland! Is this “sport” becoming a national tradition? So far we know, that beer floatings are being organised in the following towns in addition to Helsinki:

Tampere, Pori, Salo, Kouvola and Kuusamo (awaiting information). In the floating map below, you can see where people are floating in 2015.
