whay dont supercross guys use radio's even if one way from the mechanic.i always thought the pit boards were gay and there always in the way and the riders only see the boars for a second.if the rider had a ear peice and a spotter like nascar if would help the rider so much,keep people from getting jumped on and such.i was thniking about it today at work and thought you would know.cant say that it is to bumpy because pro quaterbacks use them and they get ear hole'd all the time.
