Final vote for the location of the CIS-2017 tournament.

Every year, they managed without voting.

I'll correct you here. In 2010, the contenders were Kyiv and Michurinsk. (At the same time, Nagan openly "sabotaged" Michurinsk's "application"...)
In 2013, the options were Odessa or Minsk. They decided on Odessa without any fuss, and Minsk was chosen for 2014.
In 2015, there was a discussion that went without any major conflict. The candidates were St. Petersburg and Volgograd. St. Petersburg didn't put in much effort, and Volgograd was chosen.
And this year, it could have been done without any fuss. But Vigo, with his loyal supporters, felt the need to stir things up.
