This was my second time in Osijek, Croatia for the Pannonian Challenge on the river Drava. They have run this contest for 19 years now featuring skateboarding, in-line skating and BMX freestyle. We judged an amateur event with around 40 riders coming from all across Eastern Europe and then a pro contest live on the internet. Even the Croatian president came to watch the event
