Jim, there have been times when we have had to resort to swapping people in and out of turns to get the manpower needed to comply with the Comp Regs., but it's a challenge for the turn workers.
If you are working with a new person for a full day or weekend it eases our stress load a bit, but to have new people pop in an out is not something that works. And although the turn stations gives you a great viewing area, they are not allowed to be used as such.
I would encourage all drivers and crew to come work a turn on a weekend that they have decided not to race and have the dedicated time.
I have often said that as a turn worker, I learn new things from a driver's prespective whenever I have had the opportunity to work with a driver on a turn. The drivers have learned from us too. It's a win win. (and yes, we do have a lot of fun out there and have great junk food)
