Dick Pound was trending on Twitter earlier. Not because, you know, the Olympics are in danger, but because his name is Dick Pound... Dick Pound
We saw that a lot from Rio with Zika. I don't think it would necessarily happen here. If the Olympics are deemed safe to go on and the virus is under control, I don't think it will necessarily scare off that many people, particularly tennis players who will have been in Paris and London over the summer.
Eh, I doubt this would add fuel to the fire for those guys. Considering what the Olympics have survived through (only World Wars have stopped them), it would be a pretty devastating hit for a virus to cancel an Olympics. The NOlympicsLA folks are fighting a battle that likely only mother nature (or some foolishly hungry Chinese looking for an exotic snack) could beat them at.
