I should focus my objective: Belgrade. A simple escape, not a long-term plan -- as in the first visit some years ago, when I had enough on hand for a month or two, and found a job (in India) when I got there. If I aim at the Balkans in general for an indeterminate time, I might miss it entirely.
But I know that if I can get to Belgrade, I can think clearly and get a few things in order. Read Henry James and the Strugatsky bros. in Studentski park, haunt the balconies of the national theatre and JDP at $5/ticket. Write.
Or I might veer to Sarajevo at the last second. But I do have to get there, wherever there might be.
