Hand get stuck with the car..

Why did their hands get stuck with the cars? Nights and days..
It's an activity called 'Subaru Impreza Challenge' that happens annually. It started from last Saturday till now...

These year, they are giving 2 cars to people who can stick their hand till the last. Contestants can only have 5 minute break in every 6 hours....

There are men and women categories, but I saw more women left other than men...

It's very tough, and it's surely not a challenge for me at all... @_@..!
