I saw that soccer is the national sport of Paraguay. It is safe to go watch a live game?
It's pretty safe as long as you don't wear any of the local teams t-shirts... buy tickets to either platea or preferencias and you'll be ok. The best matches are always played at Estadio Defensores del Chaco... I'd recommend you to go when Paraguay's team's playing, rather than one of the local teams... the international matches are far more interesting and safer to be at over 5 years ago
