ScottyBobby, Let’s start with the crew chief question: I can only speak for myself..YES I have a crewchief. She turns 7 this Saturday.
OK, seriously, it is just nice to have someone in the pit with you to help lifting the kart on/off the stand, helping you turn wrenches, handing you beers at the end of the day, etc. So bring a buddy.
Go to the race at IMI on Sunday and just walk around asking a bunch of questions, everyone is very eager to help someone who is new to this sport. Welcome to Colorado Karting.
