I'll add that I'm a giant fan of GTWorld on YouTube, as referenced above.
I don't want to give any information away, but there's likely to be someone named "That Guy" that's watching, but not always active in chat. Also, that "That Guy" guy needs sleep so probably won't watch the full 12 hours this year. "That Guy" will stay awake for a few 24 hour races (including the recent Daytona race), or at least nap sporadically.
If you happen to watch the race, look for "That Guy" - even 'after hours', which is after I close Linux.org for the night and don't worry about it until the following day. If you see 'em, feel free to say hello!
Also, "That Guy" is a horrible name choice. Any time someone says 'that guy' in chat, it highlights it as though they're talking to me. Lessons were learned...
If you're not into GT/endurance racing, you should be! You can see people with a lot of skill (and a whole lot of money) racing top of the line supercars. My daily driver is an M6 Competition which shares more parts with the race car than it shares with the road-going car. It's known as 'homologation'. You'll see Ferarri, Lamborghini, Porsche, Audi, BMW, McLaren, Ginetta, and more. I think they even homologated a Mustang, if you're a fan of American muscle.
They change drivers and race for up to 24 hours straight. This one is just 12 hours - but it's on The Mountain. If you're unfamiliar with Bathurst, it's amazing! As you cross Skyline and head into the twisties, there's like no margin for error. There will be some mayhem that mindlessly causes millions of dollars in damage to the field of cars going through.
It's glorious!
This is up there with the 24 Hours of Nurburgring, Le Mans, Spa 24 Hours, Daytona 24, etc...
Also, I miss Brock (Peter Perfect). Back in the days when I'd only be able to see snippets of the race coverage here in the US, he was a heck of a highlight reel. Being able to stream the entire race on YouTube is one heck of a good thing. Brocky was the greatest GT racer Australia has ever had - and the numbers show it. He truly was King Of The Mountain.
(Also, that's Mount Panorama for my non-Aussie friends. I should probably mention that.)
