Whow,
I’m in Rio once again and staying in Copacabana. Last night between Midnight and 3 am there was a helicopter right above our house for about 3 hours – for once I wasn’t feeling well and wanted to sleep early – which was impossible with that noise.
Everybody on facebook just asking what was going on.
But maybe it had to do with yesterday’s shooting in Copacabana.
