ČAG Fireside:
I arrived to an empty gymnasium after sunset, all the windows were dark, nobody was there. Three more people arrived, confused just like me. All of them were students, so they tried to connect to Eduroam. Sitting on the street, they managed to join in and I had to borrow a phone from them, since I was not a student. I suspect someone was holding a virtual gathering from somewhere, maybe using the eduroam network, since it connects the schools using it.
