You've heard of the X-Men, even the X-Files...well this is the X Games and it doesn't get any more 'X-treme' than this!
"It's one of the few sports where passion can take you all the way up to the top. You know, anybody can do it," said fan, Jason Palmer.
He's talking about BMX and skateboarding where most of the magic happens in mid-air.
The fun started on a big vert ramp in front of the Capitol Thursday afternoon with a demo by legendary skateboarder Tony Hawk -- and then at Circuit of the Americas for the rest of the weekend.
Caren Swanepool is here all the way from Namibia, Africa.
"Oh I love it! I ride skateboard, BMX myself. Not as good as these guys but I love it and I've been watching it all the 10 years in Los Angeles and just planned this year, why not come to Texas for it," she said.
As the athletes practiced Thursday, wide-eyed spectators watched through fences, from building-tops or from lines waiting to get in.
Siyarra Williams from Round Rock brought her little cousins with her.
"He's so excited, he just wants to sit here. He doesn't want to walk anywhere. He's afraid that he's going to miss something as soon as he turns around," Williams said.
And she loves this stuff too.
"I do, I think it's great! It's kind of like a family thing," she said.
Speaking of family, Rob Reed brought his son Griffin who skates a little himself.
"All my friends do it. It's really fun. It's just one of my things," he said.
Unlike some other sports, this is something really anybody can enjoy just by watching these athletes fly through the air --- like Peter Sajovich. He's from Austin so he just showed up!
"I just wanted to see what it's all about," he said.
The first night of the X Games will be wrapping up tonight with a concert by "Holy Ghost" and then the action moves over to COTA for the rest of the weekend.
Somebody you might not peg as a skateboarder, Governor Perry himself will present the first medals to the winners of the BMX vert competition.
