It's Friday, so tell me what's happening

Okay, I will, and a lot is going this weekend:

The WRC is in Japan, so another chance for Marcus Gronholm to take back two more points from Seb Loeb. At this rate he only needs about 20 more rallies and he'll be champion....

World Superbike is in Assen, scene of Troy Bayliss' season-defining crash in 2002 that allowed Colin Edwards to fight for the title at the last race in Imola. Bayliss is back, and I'm sure he'll be very quick.

The AMA Superbike paddock heads to Road Atlanta. Surely another Suzuki-fest is on the cards but the question as usual is "which Suzuki will win?"

Canadians get a chance to see the ALMS this weekend at Mosport. This should be the last time we have to suffer small grids in the ALMS this season, since the final two rounds, the Petit Le Mans and the Laguna Seca 4 Hours, will be chock-full of new arrivals.

The World Touring Car Championship returns to Europe, Brno to be exact, after it's trip to the Western Hemisphere. As I discussed here, this series is extremely exciting, so I can't wait to see how the weight-handicapping lottery will affect the results.

I missed out on discussion of the last two rounds of the DTM from Norisring and Nurburgring, and therefore didn't get to mention how Bruno Spengler won his first two races for Mercedes. We'll see if he can continue the streak amongst the sand dunes of Zandvoort in the Netherlands.

Down in Australia, the V8 Supercars have their first of two enduro races, at Sandown Raceway. Check out my mid-season roast for more info.

The fourth of the touring car series in action this weekend is the British, who head north to Knockhill in Scotland. This one's always exciting - something about Knockhill makes for tight racing.

The FIA GT series has their second French race in two weeks, moving from Paul Ricard to Dijon. Lamborghini returns, along with the debut of a Pagani Zonda.

Finally, here in the States, the US Rally Championship is in Tennessee, for a tarmac event (not too many of those in the US). Entry list thus far is a bit thin, with 25 cars, so heopefully they'll snag a bunch of last-minute arrivals.

That's it. Luckily it's a three-day weekend, so plenty of time to keep track of all the weekend's goings-on.
