How about being carfull when your opening your doors in the staging lanes. Some of the lanes are quite narrow without much room to open your doors all the way. I have a nice little scratch and ding about the size of a quarter in my passenger door from someone in the Sportsman class flinging the door open into mine. Show some respect for others property. Also dont be leaning on someone elses car or hanging your head through the window.........cant tell you howmany times I have had someone leaning against my car when I come back from using the bathroom.
