I am saddened by the lack of organized spoiler fandom, now that Buffy & Angel are gone.
That said, I have seen most of the TAR premiere (they always cut off the last twenty minutes to prevent people from giving away the ending), and can answer any questions about it that people may have.
There is already one guy, Jonathan, who makes Colin look like Miss Manners. I really hate him. A lot.
In the first ep, they start off from Chicago, and head to Iceland. There is an amusing bit with the teams trying to find the subway (the rules won't let them take a taxi), but they all seem pretty together wrt figuring out which of the three possible flights is the best one to take. (Which at this point doesn't much matter b/c the flights land within 5 minutes of each other, and in the first half of the race, as long as you don't come in last, you'll do all right.)
Iceland is freaking gorgeous. I want to go there. The teams have to drive themselves to a waterfall that none of them can pronounce, which makes asking locals for directions really, really funny.
Since nobody can read their maps, most of the teams end up deciding to follow other teams, which works out well for some, and not well for others. Team Brooklyn, for example, decides to tell Team Queens to follow them, even though they've already been to the waterfall to pick up the clue, and are heading to the Detour.
For some reason, the dad in Team Spydaddy won't let his daughter drive fast enough to pass other teams on the road, and so they fall behind REAL fast. His theory seems to be that the other teams will all get into horrible car crashes and kill themselves, leaving them the winners. In practice, what happens is that they get places much much slower than the other teams.
The Detour is a choice between taking a boat through some icebergs and looking for the route marker, or climing an ice wall. Most of the teams climb the ice wall. The clue they get directs them to the biggest glacier in Iceland, where they take a shuttle ACROSS THE GLACIER AND THEN THEY GET TO RIDE ICEMOBILES ACROSS THE ICE. It's so so so so cool. And so so so so beautiful.
There are three shuttles leaving in the morning, and the teams must choose one. When they pull a ticket off of a tent, that's their shuttle in the morning, and their tent for the night. Team WWF does some wrestling before they go to bed, and all the other teams stand around and watch.
And then the tape cuts off. Bastards!
