This year I realized that the weight is a really important thing if you want traction.
In my grandpa's farm there was a truck that couldn't move because the tires were sliping on the wet sand. We put a lot of stones and sand bags on it and then we managed to drive it away.
I think it's important to be pretty close to the weight limit to have more traction, and I think its a good thing that since 2001 we don't have the "FeatherWeight in the Finals" Award.
