The Horgos camp is next to an official transit zone between Serbia and Hungary. It took about 20 minutes for reporters to cross into Serbia and about two hours to return, as Hungarian officials checked the trunk of most vehicles.
Sayed Mohsen Shah, the elected leader of the Horgos camp, hands his portable battery pack to Serbian authorities each night. It's the only way he can make sure his phone gets charged, so that authorities can reach him.
As camp leader, Shah keeps the list showing when refugees will be allowed into Hungary. The country permits 15 people from the Horgos site and 15 from another border camp to cross the border each day. Some single men could end up waiting for two years.
While the migrants living in Bristol Park have no tents, they do have free, Telenor-provided Wi-Fi. Migrants aren't allowed to cook, so Info Park -- a refugee aid center set up in Bristol Park -- distributes hot meals. The aid center opened last September on the day Hungary sealed its border.
Every so often, rumor comes that Hungary will open its border for a few days. The men living in Bristol Park quickly pack their belongings, sell or trash what they can't carry, and run for Horgos. But Hungary isn't opening its border anytime soon.
