I will share my first-hand experience recently on a colectivo. Saturday, August 7 was a very warm winter day, so I wanted to walk in the forest of Palermo. I got on a crowded bus for Plaza Italia, but after traveling only six blocks on Av. Jujuy, the bus was at a standstill and had to make a detour to avoid the protest demonstration on Av.Rivadavia. I started walking and took the H line subte to the end of the line. It was very crowded. Standing room only like the colectivo. I have no special permission for colectivos or subtes and didn't see anyone denied travel. Masks are required.
