Ever heard of planking? You probably did after Wednesday, because that was about the only thing that was really going on at the Indianapolis Motor Speedway.

A number of drivers layed out with their legs stretch out and the arms the same by their side, doing so in usual place around the speedway.

Tony Kanaan did his on a bike, Tomas Scheckter did so on his helmet, Will Power and Ryan Briscoe did so on tires, and others were posted on IndyCar.com throughout the day.

"A lot of messing around with the other drivers," is how Scheckter described the tradition on Wednesday, but such activities might cease if indeed the clouds finally break on Thursday and Friday.

Only one day has not been effected by rain so far during Indianapolis 500 practice, and that Monday run came during relatively chilly mid-50s temperatures. A few teams have had little time to get their cars on the track, meaning their chances to get it ready before pole day qualifications on Saturday might be slim.

"If its dry, there's going to be 40 cars out there as well because they just need to make up time," said Fox 59 racing analyst Arie Luyendyk of the potentially busy track on Thursday and Friday.

Weather may finally cooperate for the drivers over the next two days with temperatures expected to be in the mid-to-upper 70s with sunny skies in the Indianapolis area.

That would be a welcome site for Dan Wheldon, the 2005 Indianapolis 500 champion who is trying to get adjusted with a new team this May. He's only had a few opportunities to get on the track with his number 98 William Rast machine with Bryan Herta Motorsports.

"I haven't competed in the first four races, I'd love to be on track," said Wheldon, and his opinion is shared.

Seven rookies wil try to qualify for the first time on Saturday including Charlie Kimball, who is working with Luyendyk this month.

"The big teams they roll out and they come out here and they're fast in four laps," said Luyendyk, who figures to be a busy man over the next 48 hours.
