Bosnia and Herzegovina
Bosnia and Herzegovina is one of the poorest countries in Europe but you might still be able to find useful things in the trash like furniture or clothes. Try farmer food markets at closing time: suggest to vendors to help with cleaning up in exchange for food.
"I spent there 5 days of hitchhiking around country and I´ve never had to buy a food. There are many markets and small shops to find fruits and vegetables. You can also always find some bread in plastic bags on street. Not bad country for dumpster diving. But I was there in summer, in the rest of year it could be different." - Král všech moří, August 2016
