With all do respect to Voodoo, everybody in the race wants to 'stay at the front' and that is what makes it hard to do! The pack is always ebbing and flowing. You could be in a prime spot, one or two places back from the front when someone attacks. If you are boxed in and the guys in front dont respond untill half the pack has passed, then your prime spot turned to poo and you have to work your way back up. On the last couple laps if the pack is all together, everybody gets antsy and that is when all the crashes happen - riders trying to stuff their bike in a spot where it won't fit.
