Not too sure where to post this as its more a suggestion than a change, but I'll put it here anyway.
I wouldn't mind seeing a Night Time start line. This has never been done before and could work out great.
Here's my thought.... Phil has all the teams at the Start Line, maybe there's a river or lake behind them with the reflection of the moon or a city scape?
Anyway, Phil says Go, and the teams run for their bags, with fireworks going off behind them, maybe at the far side of the river. (Again, something different that would look cool)
To benefit a Night start line, there could be an ARI, NOT a Start Line Task, but more like the one in TAR Aus 2, then after that, they head off to the airport.
Now, I was also thinking, by having the teams fly out of the US at night, it would mean there'll be a chance they'll land at their destination at night, and this could cause a sort of domino affect, resulting in a higher number of night legs.
Although, CBS seem to LOVE having teams wait until sunrise, or for a building to open, before they receive their next clue, so this whole idea could just be pointless.
But I'd still Love to see this non-the-less.
