I'm quite sure they must have indoor courts somewhere to get a challenger tournament.
Well i live in Banjaluka so i know we don't have indoor courts.
But i saw game started so they probably covered 1 court with "balloon" (unless that count as indoor? xD) or something like that, i'll go tomorrow to check it.
