After hours of driving and waiting at the Serbian border in mid-September heat, the border official looks at you with indifference. "Dobar dan", you mutter, as you hand over your passport, hoping the five minute "useful Serbian phrases" Google search wasn't lying.

The customs officer wants you to leave the car and open the trunk, rolling his eyes when he sees the car filled to the brim with Club Mate, boxes full of stickers and computer equipment: It's those people again. You thank the officer, sit back in the car and hit the gas, as you hear the border guard shouting; maybe picking up your passports would be a good idea.

Novi Sad is still a little further down the way and while you drive on the marvellous Serbian roads, your thoughts drift back to last year's BalCCon. The people you met, the talks you've listened to... it's all coming back (well, maybe not the Rakija leaks, you have no recollection of what happened there). You can't help but wonder, what's in store for you this year...
