I've only watched a couple of seasons, so please excuse the ignorance.
At a couple of points during the past two segments, the racers have commented on how hot it was. Does CBS ever show on the broadcast, or post somewhere on their website, what the weather conditions were? I think it would give a bit of extra flavor for the challenges they might be facing.
Also, I don't remember there being segments in the rain or snow, but they must have happened over the years, right? The go cart race probably would have to be cancelled if it was too wet (although I'm sure that's not such a risk in Sicily). Do they have contingency plans for unsafe conditions?
Thanks for filling me in. I'll add that this season is so much better than the last couple -- I find it surprising that this round of teams is filled with interesting, likeable characters, while the All Stars had almost nobody I wanted to watch -- you'd think for a banner show like the last one, they'd try harder to select good teams.
