São Paulo

I had 15 hours outbound plus 12 hours inbound transit in Sao Paulo but why I didn't explore the town?

After asking Brazilian friends, thesw are their answers:

1. Not worth the trip, traffic so bad it might take two hours to reach the city

2. People don't speak English much, only Portuguese. U might get lost

3. Taxi can easily over-charge you when they know that you are foreigner

4. Walking alone is not safe for lady in São Paulo

So I didn't go
