In a related note- saw this on Nhraracer. Imo, this is insulting the intelligence of a group of intelligent people. I don't know that they need a seminar... just email the racers instructions. They're used to following instructions in their racing endeavors.
"The NHRA will be hosting a seminar for all Top Alcohol competitors on Thursday, April 15th at 5:00 PM PT on the staging procedure for the 4-wide event. The seminar will be hosted on the starting line of The Strip at Las Vegas Motor Speedway. We encourage all top alcohol competitors to participate."
