2016 Rotax Grand Finals will be something I never forget. The seven years previous I witnessed some of the best racing and amazing drivers jumping up on the podium boxes. This year, was a little different, as my little driver Diego Laroque was the one to be on top of the box, winning the 2016 Rotax Grand Finals in Micro Max. The last lap gives me chills just thinking about it.
