I think:
----Parking is on right side of building
----they are running right to left
----Just to the left and behind the building is what looks like a black square with right ovals. (Look at the tree by the road in front of the building and then in back of the tree (& in back of the building) is where the black square is) I think this is where the fish tanks are.
----To the left of the black square could be the shack on the hill.
I'm not too sure of the location of the tanks but the parking lot to the right of the building fits with the direction they are running.
Take a look at the picture of Joyce, Eric and Bill standing as their partners are doing fish in the box.
Bill is tall...has a green shirt and beige/kaki pants on.
Then look at the picture of the three teams running. The first team's partner on the right of the photo is wearing a green shirt and what looks like kaki or tan pants. He's tall and has a fairly larger shoe.
I looks to me that it could be Bill or the frame of the person also looks to me to fit Uchenna. It looks like that person is wearing a long olivish green shirt...and I've think I've seen Uchenna wearing a similar shirt at some point in the race so far...
If that picture captures the first three teams in then it looks to maybe that it's one of the two teams I mentioned above coming in first. But if what I read about Joyce getting the clue and opening it up without Uchenna beside her, then they would be turned away to go get the clue and lose out being No. 1.
I can't make out who is running in between the first team and the BQs...
Does this make sense to anyone else?
