I’d had four days in Rio so far (and one in Miami, better left unmentioned). I had covered lots of ground for things I wanted to see, and also lots of things I didn’t know I should see. I had eaten so, so much cassava. I had lots of things left unseen, lots of food left uneaten, and just about two days left to fill. I think I made good use of my time, but I definitely left things to do… next time?
