@RachelLeVega and Peach (RE: Flowers clue)
First of all i'd like to guess the location of this dance/play is at the Theatre that all racers were waiting to be opened in the morning... I thought it refers to annual human-chess festival...but then some of us thought that it could be one side of the detour... So it still need a clear sight on that words...
@Gator (RE: basket)
Wynona's basket is still empty, they then need to go to a specific location to pick up vegetables, while the other team member pick up some chickens/hens....
I would guess that Joey/Meghan and Mona/Beth got the later flight and catch up with the rest, thanks to HoO
All the shocked/surprised scenes from Pam (or Winnie i'm not sure) , Mona (or Beth) and Chuck/Wynona in the background are all happened inside the Museum and I'd like to guess it's a Roadblock while the other team member waiting for the other one to complete a task... Could probably searching for something hidden between all the artifacts/museum...
