I got to corner work for my first time a few months ago, and have done it again since. Have to say, it is a really good experience, and gives a whole new perspective to the race, and racing in general. I particularly enjoyed watching different driver's lines, and which lines seemed the fastest, etc.
Although I will admit, that even though all you're doing is standing there, concentrating on each car that goes by, and everything thats going on in the radio is actually quite exhausting. I slept like a baby each night after the races. (weekend event).
Anyway, do your events also use a pace car/double yellow? that was the one flag i didn't see on your list, so was curious. Good write up.
